Hi,
I recently converted filesystem (reiser3.6) containing lots of small
files (400000 files, about 10 bytes each, Cyrus IMAP quota files) to CDB
database format (http://cr.yp.to/cdb.html plus some patching to make it
read-write), thus gaining significant performance improvement (load avg
was 5, became 3).
What is the best way to do the same for other similar small files, using
Reiser4? As far as I can understand, I could:
1) just put everything on Reiser4, with no changes
2) write some plugin for Reiser4
Is it possible to reduce file size on disk by not saving file ownership,
modification time, etc.?
How much kernel's VFS interface, switching to kernel and back, directory
caching, etc. does slow down these operations?
Best Wishes,
Viktors
