Hi, I have been trying to run xenmon in its logging mode to collect statistics for offline analysis. However I notice that at an interval of 100 ms or so the overhead imposed by dom0 is quite high , with upto 40% of CPU utilization. Are there ways I can drastically reduce this overhead ? I read somwhere about event overhead, using event masks and python overhead, but am not really sure how to use this information to reduce the overhead. Any help is greatly appreciated ! thanks, Ashish _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
