Max in a couple of earlier messages you made a couple of points regarding
performance tuning for iMS SE.
>The 2 biggest performance improvements I've found over the last couple
years were to split up the incoming mail files into separate >olders (vs.
storing all incoming mail into one folder, which is the FusionMail
default), plus enabling a large MX cache in the POST >server. The latter
helped tremendously, as iMS POST used to regularly run the box out of
memory before I increased the cache >setting x10 (to 5000). If you're not
using this box to store a bunch of mail on, then the former will make no
difference for you.
When you mention incoming mail files does this apply to iMS SE ? As iMS SE
is primarily for out going emails is there a way to split up the incoming
mail files? and what incoming mail files are you referring to? You would
only have incoming mail files if you were using SMTP / POP and the MX
records were pointing to the iMS box right ?
>One performance suggestion I have is to perhaps split up the outgoing

performance drags when this happens (especially on slower
>machines). I've been recently playing with the Postfix MTA (on Linux, as
a gateway mail server) and it does this to increase
>performance when sending a lot of mail (you can actually define how much
the outgoing queue is split up in order to tune it for >your volume).
Do you mean split up the outgoing queue directories to sub directories on
another server or on the same box? Can you please explain how to do this
please...
Thanks a ton.
