I think there are two reasons to a slow server-manager answer:
memory and disk
CPU isn't a importa matter because most of time isn't used. You'll use CPU to do backup (compressing)... not to read something from disk.
Why DISK is important?
Because if you have a old disk (< 20Gb) you must have a <1Mb cache on HDD.
If you're using a very old computer (< PIII) you must have just UDMA2 (< 66Mbps) support. And you can even have no UDMA enabled!
Why memory is important?
If you have less than 128Mb you have no space to cache and most of you try to access is read from disk (and I bet your disk is slow!)... so take time to read.
Upgrade your memory to at least 256Mb and you'll note some benefits... but if I can give you my 2 cents advice: get a faster disk and interface.
Just to let you know, when running this command on your SME what you get?
hdparm -t /dev/hda
This is my server:
[root@tigre root]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 1.78 seconds = 35.96 MB/sec
[root@tigre root]#
I'm using as server an EPIA 5000 with 128 MB RAM and a 80Gb HDD with 2MB of internal cache.
See this:
[root@tigre root]# hdparm -i /dev/hda
/dev/hda:

Post your numbers... I can give you another number for very different CPU/HDD but need your number to understand what can be improved!
