I recently installed kernel 2.6.19 in my slack 11.0 (to get a wireless mouse/kbd combo working right) and everything works fine except the file system (reiserfs) that is VERY slow. To confirm this, I booted up with 2.4.33 (which came with slack) and copied a ~350 mb file. It took 16 seconds. Then I tried with 2.6.19 and it took more than 3 minutes and while it copied the system was slow as hell. Its also noticeable in every program I use like playing music, firefox, etc. Everything that uses the hd a little its slow.
The kernel config options for the reiserfs I used are
# CONFIG_REISERFS_CHECK is not set
# CONFIG_REISERFS_PROC_INFO is not set
# CONFIG_REISERFS_FS_XATTR is not set
I think there is nothing wrong there.
Is there any other option that will mess so much with the fs/hdd?
