Solaris 2.6 performance oddities

Hi People,

I am currently running OpenLDAP 1.2.7/SleepyCat 2.7.7 on Solaris 2.6 SPARC. It
runs sweetly on an Ultra5 and an Ultra1. By this I mean that I have a database
of about 2000 entries and doing a complex search (similar to what outlook does)
I get results within 0.5seconds.

On two other machines (another Ultra1 and a dual CPU Ultra2) it takes about
twenty seconds to do the same query.

I had the same results with OpenLDAP 1.2.6/SleepyCat 2.7.5.

All machines have the latest patches on them, the same database and the same

I have tried all sorts of options like configuring --without-threads and so on
but it does not make any difference. I have also tried a few kernel tuning
options but they do not help either.

Has anyone got any clues as to where I could look next?
