domain controller will definitely be slow especially when it is also
acting as a file server.
the problem will also be aggravated when the system disk is the same as
the data disk
or the netlogon directory (for the domain controller) resides on the
same disk with the
file server directory.

the bottleneck is not on the CPU / memory. it's on the disk. you can
monitor the disk IO
speed of the server by executing the command:
hdparm -t /dev/disk
# hdparm /dev/ida/c0d0
/dev/ida/c0d0:
readonly = 0 (off)
readahead = 256 (on)
geometry = 8711/255/32, sectors = 71081760, start = 0
how can i see the performance of each drive? there's no /dev/sda
performance degradation is noticeable when the IO speed is below
10MBytes/secs.
make it a point to maintain not less than 20MB/secs IO speed during
"peak" times
as your baseline and in order to make the production users happy :)
