Slow on Linux 2003-11-25 - By Wade Chandler
Back
Just wondering. Did you know that every Postgres connection creates a
system process, and not a thread? PostgreSQL uses Fork. I don't use it
because of this. DB Connection = Separate Process. I use Firebird.
You can use Firebird 1.5 even. That's just a consideration since you
are posting about performance.

I have read that Suse linux team has been working closely with AMD to
support AMD64, and I am going to try their commercial product
(professional edition, $130).
I know that SUN plan to have an AMD64 version for the JDK 1.5, which
should be next year.
The reason for choosing the Linux OS is not Java, but the database. I
plan to use PostgreSQL 7.4, and they have a builds for suse x86_64, so
it looks promising.
