Here, we can see that there is a gain of ~15% to ~38% at higher client count.

The attached document (perf_write_clogcontrollock_data_v6.ods) contains data, mainly focussing on single client performance.  The data is for multiple runs on different machines, so I thought it is better to present in form of document rather than dumping everything in e-mail.  Do let me know if there is any confusion in understanding/interpreting the data.


Forgot to mention that all these tests have been done by reverting commit-ac1d794.
