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
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.
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.
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.
Arduino RGB Mixer
This can only do about 22 full frames per second. The loop time increases to 2000uS.
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.
TODO
The average isn't the best measurement, we should use the working time for just dmx queries.
