Re: Maildirs in Debian

Some would say, the solution would be to delete messages instead of hoarding
all your mailing list email which is more than likely archived automatically
by the list manager anyway (one would hope - I haven't actually checked, but
I'm sure theres got to be an archive of the debian lists somewhere).

There's no way I'd consider keeping more than about 30 messages on hand at
any one time for any mailing list - I simply dont see the point in clogging
my machine up ;)

Opening debian-isp with a mere 6000 messages takes approximatly 30
seconds here. The NFS server is a P2 400, hd is some lvm scsi raid1, NFS
client a P3 500 and the link is a Fast Ethernet (3com) with no load at
all. I'm currently using ext3 on the server.

I hoped to get some performance gain from switching to Maildir and it
certainly has its advantages (locking) but I seriously consider going
back to good old mbox which took perhaps 3 or 4 seconds to open. Opening
debian-bugs-*, -devel or -user takes _minutes_, it is simply no longer
