Summary: Performance problem

Initial Comment:
Hi,

I'm trying to do some performance tests using the
latest tm4j API. I created generic topic maps (10.000 -
1.000.000 Topics) and wanted to compare the performance
of the different storage backends. But already trying
to load the smallest Tm into a MySQL database takes
more than 10 minutes. Is this a database problem or
does it take the backend simply that long? 
I'm using Mysql version 4.0.13, java sdk 1.4.1 on a Win
XP system.

thx

georg

There is definitely a performance issue with the SQL
backend. The latest version (0.9.1) addresses some
performance issues related to indexing in the database and
to URL parsing, but the import time for a topic map is still
very long. I'll be trying to look at this issue before the
1.0 release.
