Re: Poor performance on Solaris

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 SPARC Enterprise T5120 memory:32 GB RAM os: Solaris 10 s10s_u9wos_14a searches (avg/second): 1521 box2: hardware: AMD 64 phenom 9850 memory: 8 GB RAM os: Linux dsv00000 2.6.36.2 #1 SMP Mon Dec 27 10:09:29 CET 2010 x86_64 AMD Phenom(tm) 9850 Quad-Core Processor AuthenticAMD GNU/Linux searches (avg/second): 22968 I am looking for some hints to improve performance on box1 to a similar level as on box2 or an explanation why on box1 performance is so bad. As slapd.conf, ldap.conf and DB_CONFIG are identical there should not be such a big gap in performance.
