The current Linux scheduler makes one big assumption: that 1ms of CPU time is the same as any other 1ms of CPU time, and that therefore a process makes the same amount of progress regardless of which particular ms of time it gets.

...only found the usual "improving performance for small files" hints. All these suggestions have been tested but did not or only slightly improve performance. Can anyone please tell me ... - Is there a way to check the amount of time that the different parts of a file operation take (like 1ms requesting metadata, 1ms receiving metadata, 123ms reading blocks from OST, ...)? - Does anyone have a hint on what could be the problem, where to search or what to do? Any help is much appreciated! Thanks! Robert

Hi, This is my second day since owning empire total war. Really looking forward to playing it, but I have not. I'm using the latest wine program. I follow the winehq 's description for installing empire total war (installing d3dx9, changing registry, placing MSVCP80.dll at system32 and winecfg). Now, I'm stuck at the startup page (where all the copyright details are). Loading stops

...r buffering, and Asterisk will just forward the frames, correct? What happens if the peer does not support jitter buffering, but is close by so there's no need for jitter buffering? My situation is that I have an Asterisk machine right in front of our provider's systems (same switch, < 1ms latency). If they don't have jitter buffering, how can I force my Asterisk machine to jitter buffer calls from my users to them? Thanks, -Michael

I am measuring the performance of one TCP connection over two symmetric paths. Packets are sent to two paths alternatively. I found that when the latency of each path are within 1ms, the overall TCP throughput is the *sum* of the throughput of the two paths. However, when the latency of the two paths increases to 5ms, the overal TCP throughput drops to the throughput of a *single* path. Has anyone studied similar problem? What makes the performance go down? I use Fedora Core...
