* * Implemented some tweaks to monitoring module.Adam Frisby2009-11-021-0/+3
| | | | | * Output is prettier & more useful. * Added 'Alerts' to allow rules to be constructed using Monitors to detect for events such as deadlocks. This will be translated to SNMP Traps when I get SNMP implemented.
* * Implements new 'Monitoring' system for reporting performance.Adam Frisby2009-11-011-8/+51
| | | | | | * Mostly the same set as the StatsMonitor used for Viewer notification, but exposes some new frametimes - including EventMS, PhysicsUpdateMS, LandUpdateMS; new memory monitoring - both GC.TotalMemory and Process.PrivateWorkingMemory64; also exposes ThreadCount (using System.Diagnostics.Process) * Type 'monitor report' on the console to see output. * SNMP Implementation forthcoming.

* Move the calculation of time dilation from the scene to the physics engine. ↵John Hurliman2009-10-271-13/+6
| | | | The scene is still the one reporting dilation so this does not break the API or remove flexibility, but it gets the calculation happening in the right place for the normal OpenSim usage. The actual calculation of physics time dilation probably needs tweaking

* * Switched all operations on the list of clients that could be either sync ↵John Hurliman2009-10-261-21/+27

Thank you diva

If it turns out that loading a large OAR file or some other operation is timing out the heartbeat thread, we'll need to uncomment it
* Changing Scene.ForEachClient to use the synchronous for loop instead of ↵John Hurliman2009-10-251-1/+1
| | | | | | | | | | Parallel. This is quite possibly the source of some deadlocking, and at the very least the synchronous version gives better stack traces * Lock the LLUDPClient RTO math * Add a helper function for backing off the RTO, and follow the optional advice in RFC 2988 to clear existing SRTT and RTTVAR values during a backoff * Removing the unused PrimitiveBaseShape.SculptImage parameter * Improved performance of SceneObjectPart instantiation * ZeroMesher now drops SculptData bytes like Meshmerizer, to allow the texture data to be GCed * Improved typecasting speed in MySQLLegacyRegionData.BuildShape() * Improved the instantiation of PrimitiveBaseShape
* * Changed various modules to not initialize timers unless the module is ↵John Hurliman2009-10-231-0/+3

Ideally, the timers would not initialize unless the module was actually enabled, but Melanie's work on configuring module loading from a config file should make that unnecessary * Wrapped the Bitmap class used to generate the world map tile in a using statement to dispose of it after the JPEG2000 data is created

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids .NET remoting and a managed->unmanaged->managed jump. Overall, a night and day performance difference * Initialize the LLClientView prim full update queue to the number of prims in the scene for a big performance boost * Reordered some comparisons on hot code paths for a minor speed boost * Removed an unnecessary call to the expensive DateTime.Now function (if you *have* to get the current time as opposed to Environment.TickCount, always use DateTime.UtcNow) * Don't fire the queue empty callback for the Resend category * Run the outgoing packet handler thread loop for each client synchronously. It seems like more time was being spent doing the execution asynchronously, and it made deadlocks very difficult to track down * Rewrote some expensive math in LandObject.cs * Optimized EntityManager to only lock on operations that need locking, and use TryGetValue() where possible * Only update the attachment database when an object is attached or detached * Other small misc. performance improvements

This fixes a deadlock on m_AgentUpdates that was blocking up the LLUDP server

| | | | | | | | | | | | * There's a slight chance that this could cause a problem with regular prim crossings.. but hopefully not. Revert if it does.
| * | Optimized heartbeat by calling Update() only on updated objects.Dan Lake2009-10-131-45/+37
| | | | | | | | | | | | | | | | | | | | | | | | During the heartbeat loop, Update() is called on every SceneObjectGroup which in turn checks if any SceneObjectPart has changed. For large regions (> 100k prims) this work consumes 20-30% of a CPU even though there are only a few objects updating each frame. There is only one other reason to check every object on every frame, and that is the case where a script has registered the object with an "at target" listener. We can easily track when an object is registered or unregistered with an AtTarget, so this is not a reason to check every object every heartbeat. In the attached patch, I have added a dictionary to the scene which tracks the objects which have At Targets. Each heartbeat, the AtTarget() function will be called on every object registered with a listener for that event. Also, I added a dictionary to SceneGraph which stores references to objects which have been queued for updates during the heartbeat. At each heartbeat, Update() is called only on the objects which have generated updates during that beat.
