Speed of slapadd for BDB on a Linux machine
Hello,
I'm trying to migrate about 19 million entries from OpenLDAP 2.0 to the
new 2.3. Conversion and such things are done, but inserting the data
takes days.
I hope someone can point me to some helpful direction, because 22
Entries/sec is not too good, especially not for real life use...
I'm using the following to insert the data
slapadd -q -v -c
My DB_CONFIG looks like this:
set_cachesize 1 524288000 1
set_lg_regionmax 262144
set_lg_bsize 2097152
Our OpenLDAP version is 2.3.27.
The speed is like following (took that from the output of my insertion
script):
