Hi,

Are there any benchmarks that compare different major versions of
PostgreSQL?

Cheers,

Re: performance differences of major versions

Hello

pgbench test - default configuration

Verze 7.3.15 7.4.13 8.0.8 8.1.4 8.2.beta1 8.3beta1
tps 311 340 334 398 423 585

but pgbench is simple test and thise numbers hasnot great value.

Regards
Pavel

Wow, even though it is a single benchmark, I have never seen such a
clear comparison between Postgres versions, and the 8.2->8.3 improvement
is huge, +38% improvement.

Was that the same version of pgbench each time? Or was it the pgbench
that came with each version? I think pgbench has changed a few times,
if you are using different versions of pgbench, are these numbers at all
meaningful?

I used 8.3 pgbench. I know some problems with it.

pgbench is only one view (one dimension) on PostgreSQL, nothing less
and nothing more. Some cases can be much faster or equal.

pgbench is only one view (one dimension) on PostgreSQL, nothing less
and nothing more. Some cases can be much faster or equal.

While some queries were no faster in 8.2 than in 7.4 for me, there
were many complex reporting queries that were literally thousands of
times faster. Going from minutes (nearly hours) to a second or less.
The real issue, as usual, is "How much faster is version y than
version x for YOU?" And only you can answer that by testing. In
general, I found that complex reporting queries were greatly sped up.
Updates / inserts / deletes were on the order of a bit faster to about
twice as fast.
