51eb8facd6 Add OutgoingPacketsQueuedCount clientstack stat. 
This is the total of queued outgoing packets across all connections, as also seen in the "show queues" command.
Gives some early indication of whether the simulator can't send all outgoing packets fast enough.
Though then one would want to check that this isn't due to a few bad client connections.

05508b5c56 Add "debug lludp throttle log <level> <avatar-first-name> <avatar-last-name>" to control extra throttle related debug logging. 2014-10-02 22:30:44 +01:00

d3578e2662 Add "debug lludp data out" console command for logging outgoing data just before it's put on the wire. 
Unlike "debug lludp packet" which logs at the point where OpenSim first asks the clientstack to send a certain outgoing packet, this logs immediately before the actual send.
For low-level debugging purposes.

0514679b15 reduce MIN_CALLBACK_MS guard time. A value too high introduces a extra 
throttle and makes more packets to be sent in bursts and not in steady
 state flow.

50433e089b *needs testing, not that good* change throttles math using floats and not 
int64, etc. Limite brust bytes to the total rate client requested times a
look ahead estimation time, Avoid queues starvation with updates waiting...

986863a0cd try to reduce insane high data rate udp bursts. This needs testing on a 
region with a lot of contents. Should not affect much average rates.

ade4bf69b1 if we send wearables with ThrottleOutPacketType.HighPriority, then we

1e888d61ca enqueue also if m_nextPackets[category] is not null. This is really the 
top element of a category queue, equivalente to using a queue.peek() if
 avaiable

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.

b375f86f11 Make LLUDPServer.Scene publicly gettable/privately settable instead of protected so that other logging code in the clientstack can record more useful information 
Adds some commented out logging for use again in the future.
No functional change.

83626e60e6 Adds a configuration option to cannibalize bandwidth from the 
udp texture throttle and move it to the task throttle. Since most
viewers are using http textures, the udp texture throttle is holding
onto bw that could be used for more responsive prims updates. See
the documentation for CannibalizeTextureRate in OpenSimDefaults.ini.
Option is disabled by default.

63c42d6602 Do some simple queue empty checks in the main outgoing udp loop instead of always performing these on a separate fired thread. 
This appears to improve cpu usage since launching a new thread is more expensive than performing a small amount of inline logic.
However, needs testing at scale.

582cb89beb Add a way to put things at the front of the queue for any throttle group. 
Adds a DoubleLocklessQueue and uses it for the outgoing buckets. Added
a flag value to the Throttle Type (again) because although it's hacky, it's
the best of a bad bunch to get the message through the UDP stack to where it's
needed.
