Repeated from my original post:

Does anyone have any comments on either of these two regarding
performance (specifically SELECT speeds and memory footprint)?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Well the SELECT speed and memory footprint of mySQL are both superb.

[caveat - you need a 2GHz Pentium and 1GByte of RAM]

Hmm my working gateway email server uses mySQL, originally on a sub GHz
processor and 256MB of RAM, Got upgraded to a newer nano-ATX board
1GHz and 1GB RAM. System runs Apache and email server and several other
apps, some of them using the half dozen databases.

However the system is so lightly loaded, the real question on SELECT
speeds and memory footprint depends on

Size and complexity of database
Number of concurrent users (access to database)
Number of SELECT requests per min/per hour...
What forms of caching are being used
etc....
