I assume we can't all be as modest as Linus :)

Thanks for the information; I didn't know that they had this working
already; Time to do some benchmarking on windows...

One of the problems with the benchmark was that GreatBride in the
beginning used our ODBC driver compiled for debugging; They did later
run the benchmarks again with our normal (optimized) ODBC driver but
they still refused to use our recommended MySQL version, but used
instead an old version of MySQL on a system that wasn't patched for
multi-threaded applications; One problem with Linux is that if one
wants to have good performance with a multi-threaded program one must
patch gcc; Our MySQL 3.23 binary includes some of the needed patches,
but GreatBridge wasn't interested to do any testing with this version.
There was so many bad things done with this particular benchmark (I
have already posted a lot of things about this in different forums, so
there is no idea to discuss this further); The only good thing that
come out of it was that Compaq made an open source version of a
similar benchmark, so now we will be able to do an open source
benchmark of both products to get some real figures! This will give
both groups some better indication of what we need to improve upon,
so this is a good thing!

sorry, but I can't for the moment recollect anything special about
InterChange and ODBC.
