Subject Re: interest in minor contention issues?
Date Fri, 06 Aug 2010 21:01:09 GMT
My main concern is that I'm not primarily interested in Cassandra at
this point, I'm interested in my JDI project, and formal benchmarking
of Cassandra on each item I find is probably more work than I want to
put in at this time.  If there's an easy benchmark that's already
generally agreed upon, I'll be happy to run it first, but otherwise,
I'm basically asking if the dev group is interested in reports that
won't reach the threshold of having a demonstrated performance impact,
or if those kinds of reports are generally just regarded as annoying.
