Is there some formula or recommendation on determining what would be the optimal cache settings for a directory server (389-ds of course) with following sizes? I looked at the DS 10 Admin Guide online and am getting conflicting information. But the manual shows a table and suggests that the max size for the cn=config dbcache is 512MB. But I tried with 5GB and it appears to work fine with it, although over time start to see negative values (prob not enough cache) and roevicts while running the dbmon.sh script.
__db files = ~6GB groupRoot = 1.5GB userRoot = 20GB What values would yield best performance for: cn=config dbcache? currently set to 5GB but are still seeing lots of roevicts. As much userRoot entry cache? currently set to 21GB (hit ratio so far at 95%) groupRoot entry cache? currently set to 2GB (hit ration so far at 96%) Virtual machine configured with 8CPU, 128GB RAM. Load is in the low 20's with occasional spikes to high 20's. Paul M.
