Dear all, When I compared the performance of some application on both a Xen domU and a standard linux machine (where domU runs on a similar physical mahine), I notice the application runs faster on the domU than on the physical machine. Instrumenting the application code shows the application spends more time on popen() calls on domU than on the physical machine. I wonder if xenlinux does some

Dear all, When I debugged the execution performance of an application using strace, I found there are some system calls like open and stat64 which run faster on XenLinux than the standard Linux. The following is the output of running "strace -c /bin/sh -c /bin/echo foo" on both systems. An open call runs averagely 109 usec on standard Linux but only 41 usecs on XenLinux. An stat64
