About 1 month ago I upgraded from Kernel 2.4.20-8 to 2.4.28.
Today I noticed my sequential read speed is up by about 12%.
I don't recall making any other changes that would affect speed.
So, I guess the Kernel upgrade made the difference.
An old bonnie output:

Today:

Some things improved, others decreased.
Of course, no change I can notice on my own.
I needed to measure performance to notice.
I guess I should try Kernel 2.6 some day.
