open/stat64 syscalls run faster on Xen VM than standard Linux
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
