Am I the only one who noticed this ? I installed R9 (with latest patch from RHN) on a new P4 box ( 2.4GHz, 1GB memory). Run an awk script on a 1GB file, it took about 25 minutes run on an AIX box with 300+ MHz cpu, but more than 29minutes on this R9. Same P4 box, same script, same text file, running with AT&T's UWIN on Windows XP, only takes 9 minutes ( which is what I expect from this 2.4GHz CPU).
First I thought maybe something wrong with the awk on R9, so I run a simple grep -w "string" bigfile test, again, R9 gives much much slower performance than UWIN on Windows XP. I tried both UP and SMP kernel, same result. I don't feel any slowness with normal jobs, like gnome window operation,etc., but by this test, I seriously doubt something is wrong with R9. I asked a friend who has Redhat 8 to run the same script with same 1GB file, it runs 14 minutes on his AMD 1200XP (if I remember correctly), which seems to be fine. To make sure this is not an issue between Intel's new CPU and R9, I tried the same thing on my 800 HMz Duron CPU (256MB memory ) which also runs Redhat 9, it seems to take forever. All the test on R9 shows 100% CPU busy in user mode. On UWIN/XP, CPU shows 48% busy ( I guess that's because HyperThreading). So anyone noticed the samething ? I recommend you do a simple test like grep something near the end of a big file, see how long it takes. Since awk, sed, grep all run extremely slow on both of my Redhat 9 boxes, I can't think of any reason other than the text processing library or kernel has some serious performance bug. Thanks for your time. __________________________________ Do you Yahoo!? SBC Yahoo!
