Now you need to find out _what_ in X is taking all the time. You need to either use a tool like oprofile or sysprof to extract that information, or you need to instrument the X server to report on what requests and clients are using most of its time. The latter requires code changes to a project that many people find intimidating and/or unpleasant to work with, which is why I suggested using oprofile in the first place. - ajax -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
