bamutil diff speed ups?

[mktrost]

You could try reducing the posDiff to a lower number. But then it will be
less likely to find matching records that are aligned that far apart.

I am trying to generate 2 bam files that are the differences between 2 bams
using bamutil diff.

After trying it for a while, I find it's exaclty what I need, but it's
taken a long time (more than 10 hours and running) to compare two human 30x
builds:

~/src/bamUtil/bin/bam diff --mapQual --onlyDiffs --recPoolSize 100000
--posDiff 100000 --in1 $bam1 --in2 $bam2 --out onlyDiffs.bam

Any ideas what I can do to speed it up?
