<P><FONT COLOR="#0000FF" SIZE=2 FACE="Arial">Hi</FONT> <BR> <FONT COLOR="#0000FF" SIZE=2 FACE="Arial">Very True , but the resolution between 3ms to 20ms varies wildly even with SCHED_RR, for eg. for 5ms delay the one obtained is anything between 20ms to 30ms depending on number of threads operational (more the number of threads more is the degardation) </FONT></P>
<P> <FONT COLOR="#0000FF" SIZE=2 FACE="Arial">but even simple linux should provide predictable delay mechanism , so many application require it (eg RTP Servers where packet delay is in this range). Can We do something about this</FONT></P>
