I fiddled around with these thinking it was all glibc's fault. And that reduced the number (for seti, but didn't try with X) setenv MALLOC_MMAP_MAX_ 0 setenv MALLOC_TRIM_THRESHOLD_ -1 I do see improved efficiencies after changing those glibc settings so I am betting that to reduce the number of minor faults even further will improve efficiencies further. I don't have any history of data to look at for previous kernels, so would like to know if anyone might like to try an educated guess as to what's going on. I'll have to find some time to try with a previous kernel and see if it changes. Or maybe it's purely an application problem Thanks, Richard
