I've got this video server serving video for VoD. problem is the P4 1.8 seems to be maxed out by a few system calls. The below output is for ~50 clients streaming at ~4.5Mbps. if trying to increase this to ~70, the CPU maxes out. Does anyone have an idea?
...adding the whole profile output - sorted by the first column this time...
