This is do not understand. I thought HYPERSQL was the default db engine.
You say you're using it to server ANOTHER db? why not access that
directly through Base? Am I misunderstanding something (entirely
possible)?
I found that doing it this way dramatically speeded (sped?) up the
process.
You don't way what your external db is, and I'm curious about this.
You might try converting over to that model. I have heard that H2 DB
is actually a bit better for this purpose and that it's not
tremendously difficult to convert over to H2 from hypersql
This is an interesting option, and I'm thinking that later today I'll
install H2 and set up a test to see is the problem I'm experiencing
vanishes. If not, then it's MYSQL, I guess.
Again: Under Linux any Java database is crawling unless you use one
particular Java version which is 1.6.22.
I use Base documents with embedded HSQLDB 1.8, HSQLDB 2 server and H2
as well. The latter runs well with half a million records, a dozend
relations and no Java other than 1.6.22

Thanks Andreas. I think I'm clear about this now. Linux + java db is
currently a problem, so regression to the 1.6.22 is the way to, unless
one utterly leave Java dbs behind.
As an aside, have you thoughts to share about HSQLDB vs H2? Any good
reason to migrate to H2 (a question entirely separate from the db speed
question). I'd be interested to hear your thoughts if you have time to
share them.
