Thank you for your quick response.
If idlexp is the accepted solution then I'd like to understand how to choose correct value for idlexp?
I have quickly tested with most values. With my quick tests I could not find any significant impact on performance. Setting idlexp to maximum 31 did however cause slapd to crash with segmentation fault on my system.
The appropriate value for any environment is entirely dependent on that environment's indexing and attribute value distribution for those indexed attributes. You generally want the minimum value for idlexp that allows searches to function without performance problems. Increasing the idlexp size increases slapd memory usage. Keep in mind that every increase in the
idlexp value increases the index slot range by a power of 2. The largest
Did you mean "to a power of 2", or do you really mean "by a power of 2"?
value I've ever needed for a massively large db with wide value distributions was 22.
