Subject RE: [firebird-support] Re: Basic tests shows very poor performance

Hi Paul,

As I wrote, I did the test with isql with direct connect to the DB file, not through fb_inet_server for FB1.53 as well as for FB2.0.
I still think that something was changed between FB1.5 and FB2.0 to explain such a difference : why does it take just a few seconds for FB2 where it takes 2430 s for FB1.5 ?

BTW, I've just testing it and setting the sweep interval to 0 does not change anything for both FB1.5 and FB2.0.

BTW: did you have time to test my AIX build a bit ?

Regards,

Toon.

I believe the tests are being run on classic, so he is seeing co-op garabage
collection rather than the work being done in a GC thread...
Remember Classic doesn't do threads.

I say this because Toon, just built a 1.5.3 AIX server for Classic...
So it would be interesting to know which of the Firebird Server Architectures
are being compared to the other databases.
