I don't sorry. The data except the last test run has expired from the
polygraph build node history.

Since the test was a bit unreliable I ran it freshly against each branch
that would build when I wanted to check progress.
The last test run can be found in parserng-polygraph if you want to dig
into the logs for other measures.

branch    : Mean RPS
--------------------
parserng  : 1927.84
squid-3.2 : 1933.98
squid-3.3 : 1932.81
squid-3.4 : 1931.12
squid-3.5 : 1926.13

The fluctuation / error bars seemed to be about 1 RPS for that polygraph
workload. So it looks like almost holding steady by that measure.
