Dear lists,
  I've got one test example and tested it using linux
mono and windows .NET on the same machine.  The
results showed that the performance of linux mono is
much bad than windows .NET. 
Linux Mono:
 ArrayList strings test.............3311 ms
 StringBuilder test.................4008 ms
 Integer & Floating ADD.............15145 ms
 Exception test.....................621 ms
 Reflection and recursion...........9421 ms
Windows .Net:
 ArrayList strings test.............1109 ms
 StringBuilder test.................1437 ms
 Integer & Floating ADD.............2734 ms
 Exception test.....................4046 ms
 Reflection and recursion...........5843 ms
Machine configuration:
 RAM: 512M DDR
 CPU: Intel C4 2.0G
OS:
 Windows 2003 Server .NET 1.1 Framework
 Fedora Core 4 with mono compiled from svn

Now I try to port my aspx web application to linux
mono from windows 2003 .net framework.  But regarding
of performance, I wonder whether it is deserved.
  Maybe I lack some tips to improve linux mono
performance.  If someone knows pls help me.
  tks
  zhu
