Laszlo Hornyak has finished off the proof of concept patch that I
submitted a few months ago.
This driver implements prepared statement caching and was used by Sun
to achieve the excellent results for their benchmark.
Statement caching has proven to provide a 30-40% improvement in the
benchmark results.
Because the files are quite large I've placed the patch at http://
beaver.fastcrypt.com/~davec/cachable.tar.gz
Currently it does not compile under 1.6, but works fine under 1.5.
