Beware that the native thrift php bindings has a bug which might
change provided argument types. Check out the bug report which I

This sounds like the sort of analysis that shouldn't be done in PHP. Have you
tried Hadoop + Cassandra 0.6?

Yes I tested it with and without APC -
Yes I tested it with and without APC - it had a negligible impact on
performance.
This didn't surprise me - most of the optimization that APC offers is
in the parsing of PHP code; seeing as the benchmark is a single PHP
process the code parsing overhead occurs outside the benchmark loop.
Does any
Without APC, there should be even more of an improvement with the Thrift PHP
extension.

Hi,
I've been trying to benchmark Cassandra for our use case and have been
seeing poor performance on both writes and (extremely) poor
performance on reads.
Using Cassandra 0.51 stable & thrift-0.2.0.
It turns out all the CPU time is going to the PHP client process - the
