Constants

View Source 
const PDU_STREAM_QUEUESIZE = PDU_STREAM_WORKERS * 8

The maximum number of tasks that can be queued in total before backpressure will build up and the rests will start to block.

View Source 
const PDU_STREAM_WORKERS = 256

The max number of per-room goroutines to have running. Too high and this will consume lots of CPU, too low and complete sync responses will take longer to process.
