my currently implemented compression strategy is to run the wal block through gzip in the archive command. compresses
prettynicely and achieved 50%+ in my workload (generally closer to 70)
on a multi core system it will take more cpu time but on a different core and not have any effect on tps.
General compression should probably only be applied if it have positive gain on tps you could.
