Poor performance on Solaris

2011-02-24 Thread Juergen.Sprenger
Hi, we had some performance issues on our ldap servers running Solaris 10 sparc. I did some tests using slamd http://www.slamd.com/ and got disturbing results: ldap-service: OpenLDAP 2.4.23, setup identical on both boxes, threads=64, identical content. box1: hardware: Sun Microsystems sun4v

Andrew, Thank your for replying to my question. You can equip them with caches if you want to, or just set them up to pass the queries through to the appropriate backend server. Where a non-caching proxy is the same as a chain overlay? In the LDAP proxy solution you suggested, could I then

OpenLDAP performances on AIX?

2011-02-24 Thread Marco Pizzoli
Hi all, on the same line of previous mail about openldap performances on Solaris, I would like to know if someone has experience about AIX. I'm evaluating a deploy on this platform and I would like to know about any performance comparison/experience between AIX (5.3/6.1/7.1) and Linux. Thanks in

Keep in mind that gcc on slowaris is 32 bit, and not very well optimised by default. Linux on a 64 bit linux platform usually compiles as 64 bit, slowaris by default will be 32 bit if you use the onboard gcc compiler. Using the compiler from sun studio (since v11 now free) helps quite alot but

Sorry, but I do not agree. What I can do is some tests with my relative little user database with my specific configuration. I surely cannot encounter any problem that a more complex (or simply different) configuration would be able to. If I need to introduce a new software in my production
