Agreed but simulating real load conditions involving the appropriate 
number of read to writes and bringing the effects/benefits/tradeoffs of 
row level locking and other variosu storage mechanisms etc is very 
difficult. Khalid was just lookign to comapere what you could expect 
OOTB under both systems supported by drupal.

Everyones individual use varies but my understanding of the paradigm is 
that MySQL will continue to excel with its MyISAM engine at sites 
targeted towards a read only nature (newspapaers, publishing mediums, 
etc) due to query caching and other various table reading efficiencies. 
Heavily interactive site that utilize alot of table writes and updates 
will begin to benefit more form the row level locking and advanced 
functionality (transactions, etc) of more complicated storage engines 
(InnoDB, postgresql, etc).

Like most decisions in life it is seemingly about a trade off and sits 
on a nice continuum where many or most of use sit where there isnt a 
huge difference either way ;).
