Subject: Why is Reiser4 slower then ReiserFS v3
Date: Mon, 27 Dec 2004 13:38:12 -0700 [thread overview]
Message-ID: <231dafb5041227123867a2c873@mail.gmail.com> (raw)
I am running a Linux from Scratch system and I just upgraded to Linux
kernel 2.6.10-cko1 (first time away from a vanilla kernel) in order to
try out Reiser4 but after formatting a drive I noticed it is slower
here is the best test I could run
I have three hard drives so I took a file from one and copied it to
the others and timed it
source drive /dev/hda Reiser3 Western Digital 40gb 7200rpm
target1 drive /dev/hdb Reiser4 Western Digital 80gb 7200rpm
target2 drive /dev/sda Reiser3 Seagate 160gb 7200rpm (SATA but still
same rpm as rest so it should be the same)
time cp ~/800mb.file /target1
real 0m41.409s
user 0m0.010s
sys 0m4.364s
time cp ~/800mb.file /target2
real 0m38.318s
user 0m0.017s
sys 0m5.627s
What formatting command would I use the get best speed for the
following situation
capturing raw uncompressed 720x480x29.97 video from my pci tv card.
The best I got with reiserfs v3 was 640x480x29.97 and it would end up
making a 50gb file in 64 minutes.
