Hi,
yum got really slower a few days ago on F10, so I investigated and
found that:
(3.2.23) #yum list updates
real 1m28.446s
user 1m24.553s
sys 0m0.546s
(3.2.21) #yum list updates
real 0m7.621s
user 0m6.673s
sys 0m0.390s
this is with a few repositories, no net access, no disk access
(everything
is cached), trivially reproduceable. No yum plugins (just
downloadonly), no
PackageKit installed.
About 90 seconds of 100% CPU (2.4GHz Core 2) is a disaster.
just for fun:
set color=never in your yum.conf
and run it again.
No time difference here (2:23->2:26) for color=never on yum 3.2.23.
More than 2 minutes of cpu time on a 3.1GHz E8400. Downgraded to
3.2.21-2 from koji and the same 'yum list updates' takes 6.4 seconds.
