HI! I'm currently doing some tests with OpenLDAP on a system where the real disk devices are bound together as RAID 1 meta devices. To me slapd -q seems to be extremly slow on this systems (compared to tests on my Linux i386 laptop). After a while disks are 100% busy, CPU load is very low (<5%).
The system: Sun Sparc 4 CPUs, 8GB RAM Solaris 8 with Sun Solstice Disksuite OpenLDAP 2.3.17 BDB 4.2.52 + 4 patches Any hints whether such a setup with meta devices does affect perfomance with databases? There seem to be similar problems with another directory server product on the same system. Ciao, Michael.
