Hi, I am looking to add a new hypercall to XEN-3.4.3 and invoke this new hypercall very often (may be 50 to 500 thousands of times a sec) from a HVM guest. I would like to see the cost of this to tradeoff with performance. Could you please advice if there are tools for this or any other method that i can use? Thanks in advance. Regards, VSR. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
