Hello,
After testing OpenLDAP 1.2.8 and 1.2.9 I finished test with such results:
My database is:
Berkeley DB2 2.7.7
Database - 400 MB (does anyone uses much bigger databases?)
about 450.000 records
have very high traffic
Problem rises when I try to ldapsearch full database (looking up all
records):
Often slapd just dies without errors in error log.
I tested on Linux 2.2 and FreeBSD 3.4 and situation unfortunatelly repeats.
The strange effect effect was noticed. With OpenLDAP 1.2.8 indexing of this
database
was 2 times FASTER than with 1.2.9 (it took about 6 hours on Pentium III
machine).
ldiff2ldbm without indexing works as fast as lighting but adding indexing
for two fileds
makes it work very slowly. Is that correct?
Does anyone have samo ideas and tips concerning performance?
thx
