IDE disk speed 5% slower in 1.99.7

To help me decide whether to include /dev/random in my kernel I wanted to
measure how it affected disk access speed. To do it I ran hdparm -t on my
IDE drive with a freshly booted computer that was otherwise idle.
The speed increase obtained by removing /dev/random from the kernel was
too low to distinguish from measurement error but when I performed the
same experiment running 1.2.13 I got a 5% speed improvement.
Can anyone shed some light on this? Thanks.
