These charts show the final stats at the end of the run, after all compactions
completed. The RSS shows the maximum size of the process for a given run. The
times are the total User and System CPU time, and the total Wall Clock time to
run all of the test operations for a given compressor.
While bzip2 and lzma usually achieve greater compression, they also have the greatest performance cost. zlib actually shows the smallest size at the end of the test. Overall there's very little variation in the DB sizes, because WiredTiger writes in block-sized chunks and pads out any minor differences in the compressors.
