Where to put the log files running Linux (SLES 8) ?

I'm running DB2 UDB V8 on a pseries box with SUSE SLES 8 installed and
noticed that IF I put the log files on a raw device ,
update/delete/insert is 4 times faster than IF I have the log files on
a LVM with reiserFS so... the question is why is it 4 times faster ?
I'm running the test with the same db and dbm configuration the only
thing I changed is the path to the log files so .. IF anyone has some
ideas , pls let me know.
