thanks - the numbers are pretty convincing. I've applied most of your
patch (except the instrumentation bits), and it seems to work quite well
- one of my testsystems that had interrupt storms before can now run
IOAPIC_FAST. (i also enabled the option to be selectable for SMP kernels
too. If things work out fine we can make it default-on.) I've uploaded
the -50-39 patch with these changes included.
