2.4.19 [3]              100.0   72      33      3       1.49
2.4.19-cc [3]           92.7    76      146     21      1.38
2.5.38 [3]              107.3   70      34      3       1.60
2.5.38-mm3 [1]          100.3   72      27      2       1.49
2.5.39 [2]              103.1   72      31      3       1.53
2.5.39-mm1 [2]          103.3   72      32      3       1.54
2.5.40 [2]              102.5   72      31      3       1.53
2.5.40-mm1 [2]          107.7   68      29      2       1.60

Note the io_load value for 2.5.38 was an estimate as every time I tried to run 
it it took too long and I stopped it (the longest I waited was 4000 seconds); 
showing very clearly the write starves read problem.

Of most interest is the performance of 2.4.19 with the latest version of 
compressed cache under mem_load (2.4.19-cc). Note that although the 
performance is only slightly better timewise, the difference in actual work 
done by the background load during that time is _enormous_. This demonstrates 
most clearly the limitations in previous versions of contest.
