[Quoted] [Quoted] MySQL is not a transactional database, so it doesn't even qualify for TCP [Quoted] benchmarks. A custom C to an ISAM file database is orders of magnitude [Quoted] faster than Oracle, and much faster than MySQL, but it still doesn't make it a good choice.

Look up the acronym ACID and you will see why MySQL is only good as a "toy" database.

[Quoted] Postgres is the closest thing to a real database in the Open Source community, and it is well below what would be considered acceptable for commercial use, and it would never past muster for critical data.

[Quoted] There are also some issues with Linux that make it a poor choice as a database platform. Linux lacks true raw I/O except through extensions such as from SGI and Red Hat (version 6EE). These kernel extensions bring Linux closer to the I/O performance of NT or Solaris, but not equal. With *identical* hardware, commercial databases actually run faster on Windows 2k than on Linux (usually by a factor of 2 or more for Oracle).

[Quoted] Open Source has its place. Databases is not one of those places yet. I use [Quoted] [Quoted] Linux daily as a testing and development platform. We also use it as our production web server, mail and news platforms. However, we wouldn't dream [Quoted] of using it for a production database. I have benchmarked Oracle on NT compared to Oracle on Linux, and my Linux box was twice the machine of the NT box. Oracle on NT was faster.

[Quoted] Our production database platform is Solaris, which has proven to one of the best choices as a database platform.

[Quoted] [Quoted] I am not slamming Open Source. I am only making the point that Open Source is *not* a panacea for all our computing woes.
