Summary: Very HIGH File & VM system latencies and system stop
responding while extracting big tar archive file.
Kernel Version: 2.5.75
Status: NEW
Severity: high
Owner: bugme-janitors@lists.osdl.org
Submitter: bakhtiar@softhome.net


Distribution:Slackware v7.1 : glibc v2.1.3
Hardware Environment: P!!! 550 MHz, 256 MB RAM. HP Brio BA600

Problem Description:
1) lmbench v3.0 indicates VERY slow file handling since v2.5.74. I am using
reiserfs as a default FS.

File & VM system latencies in microseconds - smaller is better

2) System stop responding while extracting big tar.bz2 archive file; example;
MozillaFirebird.tar.bz2 (about 32MB). ps indicates that sistem stuck at tar
process (pid 3607)

I hope this report enough to solve the problem...

Best wish...
