zodbshootout still produces steamin numbers, but I didn't include them 
on the web page because they would dominate the chart.  I added the 
"warm" test after your speedtest modifications.  My cold, hot, and 
steamin numbers correspond with your cold, hot, and steamin numbers. 
The steamin numbers are about the same for RelStorage and ZEO.  See this 
page for a chart that includes steamin numbers:

That is a command line option.  The chart on the web page shows reading 
and writing 1000 small persistent objects per transaction, and the 
object count is corrected now.  (OTOH, someone could claim the object 
count is off by one for some of the tests, and if that turns out 
significant, I can correct that.)
