Firstly, there is no need to move /lib/tls out of the way - TLS emulation can be slow at times, but it does work correctly now that Xen uses segment flipping. Secondly, could you take a look where the CPU time is being spent? Is it spent in user space, or in kernel space? If the latter, could you boot with 'profile=2' and use readprofile to figure out where the cpu time is being spent ? Created attachment 112572 [details]
readprofile output
readprofile output
The output of "top" shows 79% in sys and 20% in user. The output of readprofile with "profile=2" is attached. From statement of bug #151367, it seems it's a common bug but not a xen specific one. I updated the latest gdm package it's ok now. |
