In the EWeek RDBMS shootout where Oracle and MySQL came out
the winners, they used more complex queries which would
leave the MyISAM handler gasping. However, I've seen benchmarks 
where InnoDB outperforms MyISAM noticeably even on the simplest 
selects and inserts. This seems to leave only one remaining
(but important) advantage of MyISAM tables over InnoDB - the 
simpler setup and maintenance (i.e. "xcopy" backup).

Incidentally, I find Interbase/Firebird to be very interesting.  I 
see people on newsgroups and mailing lists casually mention 
running databases in the size of tens of GB on it. It has the 
_footprint of MySQL_ (~10MB exe) with the full-fledged SQL 
capabilities (views, stored procedures, triggers, multi-versioning 
concurrency, etc...) of PostgreSQL!

Yeah, according to everyone, it takes forever to set up a
connection to an oracle database. Must be the price you pay
for all the security checks.

Linux sounds like it's catching up fast with BSD in terms
of suitability for servers.  The only area I can think of where
*BSD still has an undisputed lead is security.
