Howdy gentooers,
I am looking for a filesystem that perfomes well for a cache
directory. Here's some data on that dir:
- cache for prescaled images files + metadata files
- nested directory structure ( 20/2022/202231/*files* )
- about 20GB
- 100.000 directories
- about 2 million files
The system has 2x Intel Xon Quad-cores (Nehalem), 16GB of RAM and two
10.000rpm hard drives running a RAID1.
Up until now I was using ext4 with noatime, but I am not happy with
it's performence. Finding and deleting old files with 'find' is
incredible slow, so I am looking for a filesystem that performs
better. First candiate that came to mind was reiserfs, but last time I
tried it, it became slower over time (fragmentation?).
Currently I am running a test with btrfs and so far I am quiet happy
with it as it is much faster in my use case.
Do you guys have any other suggestions? How about JFS? I used that on
my old NAS box because of it's low cpu usage. Should I give reiser4 a
try, or better leave it be given Hans Reiser's current status?
Thx in advance,
Mike
You should have a look at xfs.
I used to use ext4 earlier, traversing through /usr/portage used to be
very slow. When I switched xfs, speed increased drastically.
This might be kind of unrelated, but makes sense.
