Re: [Xen-users] How to optimize pre-copy algorithm of xen to minimize downtime?

[Lars Kurth <lars.kurth@xxxxxxx>]

Hi,

there was a list of issues with migration performance published at 
http://www.slideshare.net/xen_com_mgr/vm-live-migration-speedup-in-xen - 
not sure this helps.
Otherwise, you really need to start looking at the code, run bechnmarks, 
profile, etc. There are some tools you can look at to help you, e.g.,
1) http://www.slideshare.net/xen_com_mgr/5-xs-asia11gdunlapxenalyze
2) http://wiki.xen.org/wiki/Category:Performance - there some articles 
on how to profile, collect data, etc. in this category
Regards
Lars
