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.
