Need stress and performance testing for log compression (WT-1359). Here are sueloverso 's comments from pull request WT-1437:

We have 4 new log related runner configurations. If a compression runner is based off one of those, we can plot it on Jenkins along with its uncompressed run and compare. log.wtperf and log-noprealloc.wtperf are the same except for log preallocation. They use small logs too. If we add a 3rd one to the plot we probably ought to increase the key/value size in all those runs to get a good comparison.
