[389-users] Performance differences between 1.1.2 and 1.2.6/1.2.7

[Reinhard Nappert]

Hi,
I noticed that the search performance increased quite a bit with 1.2.6/1.2.7.5, compared to 1.1.2.

I did a rather simple test, where I randomly searched objects from a small database with about 25.000 objects. I assume that those objects are cached.
The tests were performed on a 2 Dual CPU (1.8 GH clock speed) box with 16 GB RAM.

I did perform 7.000.000 searches with 7 threads (1.000.000 searches per thread). Both directory instances were configured in exactly the same way.

I got 5630 searches/sec for the 1.2.7.5 directory instance, whereas
I got 6890 searches/sec for the 1.1.2 directory instance.

I was wondering what the reason for the performance decrease is.

Thanks,
-Reinhard
