What is the fastest way (in terms of openldap settings) to perform a
massive load (~200MB ldif file) of data into openldap directory?
Try "slapadd -q" (read slapadd(8) man page to get started).
slapadd -q is important, but so is having a large enough BDB cache in
the DB_CONFIG file, plus setting the right number of tool threads. I
took a load down from 17 hours to less than 2 hours adjusting all of
those correctly and adding -q.
The LDIF file is only 200Mb large. It should be a matter of minutes to
load it on a decent machine, even when using the standard parameters :)
There is not a 1 to 1 correlation between LDIF file size and resulting
database size. My LDIF file was 300MB and the resulting database was 12.5
