Yep, switch to Linux :-)
Seriously, loading 150K messages takes time but 25 minutes seems a little 
bit excessive to me.

Hello

Did you use 'performance monitor' to try to detect where is the =
bottle-neck
? (cpu, hard disks, scsi controller, ram, swap, io buffers for network, =
hard
disk, memory allocation, ...)

This can help finding the source of your problem and point exactly what =
to
upgrade first ... (why changing cpu if cpu never reach more than 10% =
 or
disk sub system if disk queue workset never reach maximum recommanded
values...)

Some possibilities (depending of your current disks setup, if we talk =
only
for disk sub-system)
Are you in raid ? 0, 1, 5, ...
What is your physical/logical disks/partitions architecture
swap in raid 1 separated physical drives from data and os ?
and/or Os in own raid 1 separated physical disk
xmail data on its own raid 1 physical disk or not ?

But first a good 'perfomance monitor' trace is allways the best to =
determine
the faulty source ...

 We have several XMAIL servers and are very happy with them,
 but some have more than 150.000 mails sometimes and when we stop
 them for maintenance, then after the restart it tooks more
 then 25 minutes to rescan all the spool. To optimize this
 with have upgraded to DELL servers with SCSI drives, and we have
 allocated 32 kb blocks to speed up access, as well as suppressed
 8.3 old DOS name generation.
