basic sequential harddisk speed test

# write 1Gbyte of zeros to file
time dd if=/dev/zero of=/share/MD0_DATA/testfile bs=1M count=4096

4096+0 records in
4096+0 records out

real	0m26.284s
user	0m0.045s
sys	0m21.328s

# do the math (bc is your friend)
4096/21.32 = 4096/21.32
192MByte/Sec, pretty good for RAID5 NAS, imho

basic cpu and ram monitor script:

# or
while true; do echo "cpu load averaged over 1, 5, and 15 minutes:"; cat /proc/loadavg; free; sleep 1; clear; done

# cpu load 
# averaged over 1,    5, and 15 minutes
