Subject: reiserfs - recommendations for small files
Date: Sat, 17 Oct 2009 23:41:12 +0530	[thread overview]
Message-ID: <84c89ac10910171111n69b9832fr42d30aa07d84b262@mail.gmail.com> (raw)

Hi,

System : Fedora 11 x86_64
Current Filesystem: 150G ext4 (formatted with "-T small" option)
Number of files: 50 Million, 1 to 30K png images

We are generating these files using a python programme and getting
very slow IO performance. While generation there are only writes, no
read. After generation there are heavy read and no write. These files
are not in a single directory, this is a pyramid structure. There are
total 15 pyramids and coming down from top to bottom the sub
directories and files  are multiplied by a factor of 4

I am looking for an alternate file system and best
practices/recommendation to get a better performance. What the
optimisation methods available in reiserfs for small files?

Any suggestions of the above are greatly appreciated.

Viji
