Subject: a question about popen() performance on domU
Date: Wed, 23 Nov 2005 14:25:44 -0600 [thread overview]
Message-ID: <4384D048.1020102@cs.uchicago.edu> (raw)
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 special
modification of the popen code to improve its performance than the original Linux popen code?
Thanks in advance for your help.
Xuehai
