Subject: slapd and meta devices under Solaris 8
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
After a while disks are 100% busy, CPU load is very low (<5%).
Sun Sparc 4 CPUs, 8GB RAM
Solaris 8 with Sun Solstice Disksuite
BDB 4.2.52 + 4 patches
