* * Change Util.FireAndForget to use ThreadPool.UnsafeQueueUserWorkItem(). ↵John Hurliman2009-10-191-2/+0
| | | | | | | | | | | | | | 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

|/ / | | | | | | | | | | * OnQueueEmpty is still called async, but will not be called for a given category if the previous callback for that category is still running. This is the most balanced behavior I could find, and seems to work well * Added support for the old [ClientStack.LindenUDP] settings (including setting the receive buffer size) and added the new token bucket and global throttle settings * Added the AssetLoaderEnabled config variable to optionally disable loading assets from XML every startup.

It will be fired asynchronously as soon as an empty queue is detected (this can happen immediately following a dequeue), and will not be fired again until at least one packet is dequeued from that queue.

* From: Alan Webb <alan_webb@us.ibm.com>Dr Scofield2009-06-251-44/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves texture send processing out of the main packet processing loop and moves it to a timer based processing cycle. Texture packets are sent to the client consistently over time. The timer is discontinued whenever there are no textures to transmit. The behavior of the texture sending mechanism is controlled by three variables in the LLCLient section of the config file: [1] TextureRequestRate (mS) determines how many times per second texture send processing will occur. The default is 100mS. [2] TextureSendLimit determines how many different textures will be considered on each cycle. Textures are selected by priority. The old mechanism specified a value of 10 for this parameter and this is the default [3] TextureDataLimit determines how many packets will be sent for each of the selected textures. The old mechanism specified a value of 5, so this is the default. So the net effect is that TextureSendLimit*TextureDataLimit packets will be sent every TextureRequestRate mS. Once we have gotten a reasonable feeling for how these parameters affect overall processing, it would be nice to autonmically manage these values using information about the current status of the region and network. Note that this also resolves the pathologcal problem that previously existed which was that a seated avatar generated very few in-bound packets (theoretically) and would therefore be the least able to retrieve the images being displayed by a projector script.

| | | | | | | | | | | | Following feedback from 0003440, i've made some changes to the new texture pipeline to optimise performance. The changes are: - Fixed a math issue where a small percentage of images with a certain size (on the packet boundary) would not have their final data delivered. This issue has been present since pre- 0003440 - It was suggested that a discardlevel of -1 and a prioriy of 0 meant to abandon the transfer, this is incorrect and caused some textures to clog. - The texture throttle blocking queue is now only filled in relation to the actual throttle amount.. i.e, on a connection throttled to 300k, only twenty packets will be placed in the queue at a time, on a larger connection it will be much more. This is to balance responsiveness to requests and speed, and to minimise wasted packets. - The engine now keeps track of the number of pending textures, and the stack will not be walked if there's no textures pending, saving CPU. Textures are only considered "pending" when they've already been decoded. - As part of the above, some textures may receive twice as much data per cycle if the number of pending textures is below the cycle threshold, this should prevent loading from slowing down when there are fewer textures in the queue.

* From Alan Webb <awebb@linux.vnet.ibm.com>Sean Dague2009-02-091-2/+2
| | | | | | | | | | | These changes replace all direct references to the AssetCache with IAssetCache. There is no change to functionality. Everything works as before. This is laying the groundwork for making it possible to register alternative asset caching mechanisms without disrupting other parts of OpenSim or their dependencies upon AssetCache functionality.
* This changeset is the step 1 of 2 in refactoringDr Scofield2009-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | OpenSim.Region.Environment into a "framework" part and a modules only part. This first changeset refactors OpenSim.Region.Environment.Scenes, OpenSim.Region.Environment.Interfaces, and OpenSim.Region.Interfaces into OpenSim.Region.Framework.{Interfaces,Scenes} leaving only region modules in OpenSim.Region.Environment. The next step will be to move region modules up from OpenSim.Region.Environment.Modules to OpenSim.Region.CoreModules and then sort out which modules are really core modules and which should move out to forge. I've been very careful to NOT BREAK anything. i hope i've succeeded. as this is the work of a whole week i hope i managed to keep track with the applied patches of the last week --- could any of you that did check in stuff have a look at whether it survived? thx!
