Below are compression times for a 6.8GB SAM file. Tested on Ubuntu 11.10 with latest versions of all software. We got the latest source for each tool and compiled it on our node. Our node has 128GB of RAM and 4x AMD Opteron(TM) Processors. Total of 64 cores.

cores pigz pbzip2 gzip bzip2
2 10m32s 9m52s xx xx
16 1m25s 1m36s xx xx
64 1m6s 0m34s xx xx
1 xx xx 21m18s 19m16s

The pbzip file was 1.7GB and the pigz file was 2GB so not as big as difference as I thought.
