Justin Clark-Casey (justincc) 3555c0c3f3 Fix recent regression test TestDeserializeXmlObjectWithOtherParts() which was not meant to indent the input xml 2014-08-29 18:14:47 +01:00
Justin Clark-Casey (justincc) 305c3e668a Add regression test for deserializing xml objects with more than one non-root part. 2014-08-29 18:06:29 +01:00
Justin Clark-Casey (justincc) 1a3ffda852 minor: Eliminate more unnecessary code copying individual parameters for Vector3 copying in Scene - this is not necessary as Vector3 is a value type 2014-08-28 18:37:34 +01:00
Justin Clark-Casey (justincc) f132f642b2 On code section that rezzes single objects and attachments, reduce CPU use by reading asset XML a single time with a stream reader rather than multiple times.
Reading large XML documents (e.g. complex attachments) is CPU expensive - this must be done as few times as possible (preferably just once).
Reading these documents into XmlDocument is also more resource intensive than using XmlTextReader, as per Microsoft's own publication "Improve .NET Application Performance and Scalability"
Optimization of other cases will follow if this change is successful.

Justin Clark-Casey (justincc) 42bb122232 Fix frame times when updating scene on timer. 2014-08-26 18:13:38 +01:00
Justin Clark-Casey (justincc) 64f640f901 Implement experimental non-default mechanism to update scene via a timer rather than a persistent thread with sleep.
This is to see if an inaccuracy in sleep times under load is responsible for increase in frame times even when there is spare time still available.
Can currently only be activated by setting "debug scene set update-on-timer true".
Can be switched between timer and thread with sleep updates whilst the scene is running.

Justin Clark-Casey (justincc) fabab7414f Remove database connection locking in MySQLXAssetData. This is unnecessary as connections aren't shared and transactions are already in place where necessary. 2014-08-22 20:34:33 +01:00
Justin Clark-Casey (justincc) 0cb805a64c Remove query locking in MySQLUserProfileData. This is not necessary as the connection is not shared. 2014-08-22 20:28:56 +01:00
Justin Clark-Casey (justincc) 709038aa2a Remove some use of database connection locking from MySQLSimulationData - this has not been necessary for some time as database connections are not shared.
However, many locks remain since they may effectively be providing transactionality in some operations (e.g. prim updates across multiple tables).
These are candidates for being replaced with proper database transactions, since this would not block unrelated operations (e.g. land save and object save)
or unrelated operations on the same tables (e.g. storage of one linkset whilst another is being removed).
In practice, any performance deg due to contention is probably rare and short lived as the major prim operations are performed in memory and only persisted some time afterwards.

Justin Clark-Casey (justincc) d899bdcb9b Remove lock in MySQLFramework. This is not necessary as the connection is not shared. 2014-08-22 19:52:03 +01:00
Justin Clark-Casey (justincc) f129b824c3 Removing locking on requests in MySQLAssetData.
These locks are not necessary since the connection is taken from the underlying mysql pool and not shared.
Such locking is already not done by some other parts of OpenSim.Data.MySQL.

Justin Clark-Casey (justincc) 4e03d352c3 Extend drop command to "debug lludp drop <in|out>..." to allow drop of inbound packets.
For test/debug purposes.

Justin Clark-Casey (justincc) 298376d5c7 Add "debug lludp drop out <add|remove> <packet-name>" console command for debug/test purposes.
This drops all outbound packets that match a given packet name.
Can currently only be applied to all connections in a scene.

Justin Clark-Casey (justincc) 84cea46c10 Add experimental OutgoingQueueRefillEngine to handle queue refill processing on a controlled number of threads rather than the threadpool.
Disabled by default.  Currently can only be enabled with console "debug lludp oqre start" command, though this can be started and stopped whilst simulator is running.
When a connection requires packet queue refill processing (used to populate queues with entity updates, entity prop updates and image queue updates), this is done via Threadpool requests.
However, with a very high number of connections (e.g. 100 root + 300 child) a very large number of simultaneous requests may be causing performance issues.
This commit adds an experimental engine for processing these requests from a queue with a persistent thread instead.
Unlike inbound processing, there are no network requests in this processing that might hold the thread up for a long time.
Early implementation - currently only one thread which may (or may not) get overloaded with requests.  Added for testing purposes.

Justin Clark-Casey (justincc) 3a643e2456 Don't allow the last behavior to be removed from a pCampbot bot
If you want to stop existing behavious, add the None behaviour.
2014-08-15 22:44:31 +01:00
Justin Clark-Casey (justincc) 1d2933ca51 Resolve a small race condition on removing bot behaviours that might leave previous behaviour active
Also closes behaviours on disconnect instead of interrupt, though this makes no practical difference.
If existing behaviour is None, other added behavious will not take affect until None is removed (as this is an infinite wait until interrupted).

Justin Clark-Casey (justincc) e0c6bfa81e If a user moves back in sight of a child region before the agent has been closed on teleport, don't unnecessarily resend all avatar and object data about that region. 2014-08-15 21:47:34 +01:00
Justin Clark-Casey (justincc) 91e1aaa5d4 On teleport to a region that already has a child agent established (e.g. a neighbour) don't resend all the initial avatar and object data again.
This is unnecessary since it has been received (and data continues to be received) in the existing child connection.

Justin Clark-Casey (justincc) 4c781db572 Make RootTerseUpdatePeriod and ChildTerseUpdatePeriod configurable in [InterestManagement] in OpenSim.ini for experimental purposes.
If n > 1 for RootTerseUpdatePeriod only every n terse update is actually sent to observers on same region, unless velocity is effectively zero (to stop av drift).
If n > 1 for ChildTerseUpdatePeriod only every n terse update is sent to observers in other regions, unless velocity is effectively zero.
Defaults are same as before (all packets are sent).
Tradeoff is reduction of UDP traffic vs fidelity of observed av mvmt.
Increasing n > 1 leads to jerky observed mvmt immediateley for root, though not on child, where experimentally have gone to n = 4 before jerkiness is noticeable.

BlueWall dabb8e62f4 Update OpenID server handler with proper interface. fixes http://opensimulator.org/mantis/view.php?id=7301 2014-08-13 20:06:07 -04:00
Justin Clark-Casey (justincc) bc0895c758 On entity transfer of scene presence, replace polling sleep in SP.WaitForUpdateAgent() with a triggered event instead.
Rapid polls are more expensive than triggered events (several polls vs one trigger) and may be problematic on heavily loaded simulators where many threads are vying for processor time.
A triggered event is also slightly quicker as there is no maximum 200ms wait between polls.

Justin Clark-Casey (justincc) 0d2a25b477 Remove redundant origin region lock in SP.CompleteMovement()
This is already going to be correctly set by WaitForUpdateAgent() earlier on in that method, which is always called where a callback to the originating region is required.

Justin Clark-Casey (justincc) 0db6f3a2bd Only set up the UnackedMethod for an outgoing message if that message is actually meant to get an ack (because it's reliable). 2014-08-13 22:57:14 +01:00
Justin Clark-Casey (justincc) 21176a3a90 Terminate 'nothing' behaviour (and potentially others) by signalling using an event rather than polling connection state every 100ms
This kind of polling is very expensive with many bots/polling threads and appears to be the primary cause of bot falloff from the client end at higher loads.
Where inbound packet threads can't run in time due to contention and simulator disconnect timeout occurs.
2014-08-13 22:38:27 +01:00
Justin Clark-Casey (justincc) f1f935ed95 Add 'server' stats information to pCampbot, as used elsewhere in OpenSimulator
This adds the "show stats", "stats record", etc. commands and information on available Threadpool threads, etc.
It also adds the Watchdog which logs warnings if time between executions is unexpectedly large.
2014-08-13 19:53:42 +01:00
Justin Clark-Casey (justincc) f1cec684e2 For pCampbot, set max number of permitted connections to an endpoint to int.MaxValue
This is to avoid issues where many bots connect to a single end point with multiple regions, where each region requires a long-lived poll connection for each bot.

Justin Clark-Casey (justincc) 8738445eb7 Move the inventory request lock introduced in git master a58152bd to HGInventoryBroker to preserve that behaviour there but allow 2 simultaneous inv requests (chiefly WebFetch) rather than 1
This lock serialized all requests and made the inventory throttling in WebFetch redundant.
By moving this lock, two simultaneous requests may now take place which may help with http://opensimulator.org/mantis/view.php?id=7054

Justin Clark-Casey (justincc) 30f1b424bb Change RootRotationUpdateTolerance from 0.01 to 0.1 in code as well. 2014-08-08 23:47:53 +01:00
Justin Clark-Casey (justincc) 36f01dce2d Change MaxPoolThreads default in code as well from 15 to 300 2014-08-08 23:47:03 +01:00
Justin Clark-Casey (justincc) 91f3be71e3 Reduce default rotation AgentUpdate output sensitivity to a setting that cuts down UDP traffic without obvious adverse effects on observed avatar rotations.
Experimentally, on the Linden Lab grid the avatar can rotate slightly before triggering AvatarUpdates, whereas this is practically impossible in OpenSimulator.
These updates allow other avatars to see rotations, though sensitivity is low since other avatars can only be seen in one of 8 body rotations.
This commit changes sensitivity from 0.01 to 0.1, which better matches LL and reduces UDP traffic which has a beneficial impact on network and CPU load.
This has no impact on rotations in the simulator itself so simulation fidelity is the same as before.
To change this setting back for test/other purposes, edit RootRotationUpdateTolerance in the [InterestManagement] section of OpenSim.ini

Justin Clark-Casey (justincc) a483525016 Change default max threads if SmartThreadPool is used as the main thread pool from 15 to 300
Running out of such threads under heavy load causes delayed packet processing which can lead to spurious UDP resends and knock on issues.
We already massively boost the min/max builtin pool worker and IOCP threads (which even with STP are still used for inbound network requests) without obvious adverse effects.
The threads are only instantiated if they are required.
This change does not affect other async_call_method options.
