Hi,
It was actually a discussion between me and Alex G, who has experimented
with various filesystems. It was agreed that spool is faster and more secure
than file for storage, but the appropriate filesystem should be used. Avoid
filesystems with logging (i.e. ext3). Ext2 is a much better choice. Also
Alex had some reservations when the spool subdirectories exceeded 50,000 msg
in queue. For that it would be best to use an undexed filesystem (i.e.
Reiser) or similar if you expect high volume.
Bottom line. Pick an indexed filesystem without logging. Ext2 is not indexed
but for low queues (< 50000) it is the best choice. Optimize also mount
options (noasctime, etc.). Put spool on a seperate disk and use solid-state
for faster access.
BR,
Nikos

Hi all,
If I am able to do a completely new server setup, what would be the best
filesystem to choose? I thought I saw Nikos commenting on a mail about the
filesystem ago, and I think he said ext2 would be better than ext3?
Suppose I would process a txt file with 5 million CSV lines in it, I
suppose it would be best to have it running on an other physical disk than
Kannel, right?
Hope somebody could give me some advice, because we didn't have experience
with bulk traffic like this before.
Thanks in advance!
Regards,
Roland.
