Description of problem: a simple command 'grep -i a file' take about *half minute* in rh_9 when in other distribution like rh_7.3 take _only_ 0.02 seconds. I think that shall be a nptl(glibc or kernel) trouble because with 7.3 in the same machine and in a laptop take the correct time with older and same kernels (obviously wihtout nptl) releases. I made this test with several grep versions of 9 and 7.3 in redhat_9. 'file' is a text file of 1.2M for more details, see attachment file from the first time redhat_9 looks like to me slower and more heavier that 7.3, cron jobs take more time and the system is frozen for seconds. Galeon browser has similar problem and in general the system runs worse than 7.x in the same hardware -thanks- Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
