A simple comparison (very rough, but shows the idea):

$ time clamscan /etc/services
/etc/services: OK

----------- SCAN SUMMARY -----------
[...]
Data scanned: 0.01 Mb
I/O buffer size: 131072 bytes
Time: 0.721 sec (0 m 0 s)

real    0m0.726s
user    0m0.680s
sys     0m0.040s


$ time clamdscan /etc/services
/etc/services: OK

----------- SCAN SUMMARY -----------
Infected files: 0
Time: 0.008 sec (0 m 0 s)

real    0m0.012s
user    0m0.000s
sys     0m0.000s


Depending on which times one compares, one gets:

0.721/0.008 ~= 90  or:

0.726/0.012 ~= 60.

You can see the difference! ;-)
