[Xen-users] speed problem with java and WebSphere 5.1 after virtualizing server
Hi all! I have converted a physical server (redhat AS 3.4, kernel 2.4.21-47.0.1.EL.xs0.4.0.25xenU ) to a virtual server with Dom0 CentOS 5 32bit. The conf file is name = "SERVER" memory = "1536" maxmem = "1536" disk = [ ''phy:/dev/vg/SERVER,sda,w'', ] kernel = "vmlinux-2.4.21-47.0.1.EL.xs0.4.0.25xenU" ramdisk = "initrd-2.4.21-47.0.1.EL.xs0.4.0.25xenU.img" vif = [''bridge=xenbr0'' ] vfb = ["type=vnc,vncunused=1"] bootloader="/usr/bin/pygrub" vcpus=4 on_reboot = ''restart'' on_crash = ''restart'' At first during boot I noticed a problem with tls (thread local storage) and as suggested I moved /lib/tls to /lib/tls.disabled So I still had speed problems: I found that I had to install a optimized version of glibc build (follow this link http://www.slacky.eu/forum/viewtopic.php?t=21425) After that, I still had speed problems. Now I upgraded diskdumputils, initscripts, coreutils to the following version: Nov 28 09:19:13 Dep Installed: diskdumputils 1.3.3-1.i386 Nov 28 09:19:13 Updated: initscripts 7.31.31.EL-1.centos.1.i386 Nov 28 09:19:13 Updated: coreutils 4.5.3-28.7.i3 And I still have speed problems. When I say "I have speed problem" I mean I have very big speed problem with WebSphere 5.1. All java processes are really slow. Do you have suggestions?
