Dubiel Vitrum is using Linux Debian system extensively to manage all
documents in electronic form. We have ten million of files sorted in
directories. The biggest directories contain about 100.000 files.
Currently our system works effectively by using ReiserFs, which is
especially fast for small files and directories containing lots of
files. But ReiserFS is not supported any more, so we are looking for a
new file system that would handle our job as good as ReiserFS.
I installed fresh Debian, created empty partitions, formated them as
Reiserfs, Nilfs. Then run command on each partition:
for A in $(seq 10); do for B in $(seq 100); do for C in $(seq
1000); do mkdir -p $A/$B/$C; done; done; done
and then run:
find >/dev/null.
On Reiserfs it (last command, find) took 19 seconds, while on Nilfs it
took 170 seconds. Maybe this is because system lacks b-tree directory
management. Another limitation is that I was unable to create more than
thirty thousand directories in one directory.
