OLA Performance Stats
From OpenDMX.net
This is a brain dump of random OLA performance metrics. Unless otherwise mentioned these were performed on a MacBook Pro 2.4GHz Intel Core 2 Duo . More general information is at Pipe vs Unix Socket Performance

[edit] Idle Test
Receiving an Streaming DMX update for a non-active universe with 512 channels is 40-50uS. This represents the best-case turn around time for an RPC.
[edit] UsbPro Test
Patching the Usb Pro Output port causes the average loop time to increase to 150uS for a 512 channel packet. 200 frames/second is about the upper limit the Usb Pro can support.
[edit] E1.31 Test
Patching an E1.31 Output Port results in a loop time of 125uS @ 200fps. OLA can sustain at least 2200 frames per second in this mode, where the loop time drops to 70uS. This was tested with a single universe and 4 universes.
[edit] Arduino RGB Mixer
This can only do about 22 full frames per second. The loop time increases to 2000uS.
[edit] RPC Throughput
The maximum with no ports/clients patched is around 20k rpcs/sec. At this point olad isn't reading the data fast enough and the socket buffers fill up and we losing framing.
[edit] TODO
The average isn't the best measurement, we should use the working time for just dmx queries.
