Subject Re: [RELEASE] Apache Cassandra 1.0.6 released
Date Fri, 16 Dec 2011 12:34:30 GMT
Works if you turn off mmap?

We run without mmap and see hardly any difference in performance, but with huge benefits in
the form of a memory consumption which can actually be monitored easily and it just seem like
things are more stable this way in general.  

Just turn off and see how that works!

Regards,
Terje
