Pre-linking, AIUI, pre-generates a map of where the shared libraries
should be loaded and the symbol resolution table that the loader would
normally create when the executable is run.  This shaves off some
startup time for the application, but doesn't affect the execution
speed.

It would help here, but I couldn't tell you how much.  I wouldn't expect
more than a second.  The time it takes to load it from the drive is a
large part of the startup time.

If he already has 30M (>10% of his memory) swapped out, then more memory
would likely help him more than pre-linking.  Making sure DMA is enabled
for his drive (inspect it with hdparm) would speed things up immensely.
