Re: testing symas with slamd bad results



I suggest you take a look at:

<http://www.symas.com/benchmark.shtml>

particularly

<http://www.symas.com/benchmark-auth.shtml>

and make sure you are tuning OpenLDAP correctly before benchmarking. There is a tarball there that can be downloaded that can give you an idea on tuning.

These 2 utilities are included in the sun's Directory Server Resource Kit. if you google for file 'benchmarking_ds52.pdf' you can see the utilities also mentioned there. anyway i listened to your advice and setup slamd server. and did some searchtests.but i am very sad.because my Sun Java Directory Server out out out performed much better than my symas. i feel desperate for these results. i have got two machines both are same.System Configuration: Sun Microsystems sun4v SPARC Enterprise T5220 Memory size: 32640 Megabytes.64 cpu. one includes symas-openldap-silver-2.4.11.0.sun4u.pkg the other one Sun Java Directory Server 6.3

i first ran e Prime Job for my DB to be fully loaded to memory.
then after i did the same searches for both of these servers.
SunJava Server result for Searches Completed is :23358.974
Symas result for Searches Completed is:1814.640
my slapd.conf file is:
sizelimit unlimited
tool-threads 8
database        bdb
suffix "o=sdftest"
rootdn "cn=sdf,o=sdftest"
rootpw admin234
index        default                eq
index        objectClass
index        mobile                eq
cachesize        1000010
idlcachesize        1000010
checkpoint        256000        60
cachefree        9000

DB_CONFIG is:
set_cachesize        26                0        1
set_flags       DB_LOG_AUTOREMOVE
set_flags         DB_TXN_NOSYNC
set_lg_max        10485760
set_lg_bsize        2097152
set_lk_max_locks        3000
set_tas_spins        1

what else can i do to out perform symas to Sun Directory Server
Enterprise Edition.
i have to convince my project leader that symas is better than Sun,but
how?

and use its utility called 'searchrate' and 'modrate' for comparing these two servers' performances.

No idea in the world what those are. I suggest you look at slamd.
