Hi Quanah, Thanks for replying, I have few more observation regrading my load runs, real time of load run with MDB is 98% even at 10 TPS.
What version of OpenLDAP are you using? ---2.4.32 What type of disk? --root@tspatca2103> fdisk -l /dev/mapper/vg00-root Disk /dev/mapper/vg00-root: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg00-root doesn't contain a valid partition table root@tspatca2103> What type of file system? --ext4 (/dev/mapper/vg00-root on / type ext4 (rw,nouser_xattr)) What is your *exact* slapadd command? --/opt/openldap/yaju/sbin/slapadd -q -w -f /opt/openldap/yaju/etc/openldap/slapd.conf -l /root/yaju/db.ldif I am using jmeter to simulate the load. -- Thanks and Regards Yajuvendra On Tue, Aug 28, 2012 at 8:19 PM, Quanah Gibson-Mount <[email protected]>wrote: > --On Tuesday, August 28, 2012 5:29 PM +0530 Yajuvendra Singh < > [email protected]> wrote: > > Dear Experts, >> >> >> Today we tried with to run the load with the below schema.
