Hello, First off, my server is equipped with 12GB of physical memory. From reading tuning guides online, I’ve found that a starting estimate for the ‘dbcachesize’ = SUM(allDB4files). For one of my directory instances, the id2entry.db4 file alone is ~ 11GB. Performance wise, would it be worthwhile to increase the amount of physical memory on the server (perhaps 64-128GB)? Or does 11GB for an id2entry seem like an extremely high value that’s out of the operating capabilities of the directory? Is it unheard of for a production directory server to be equipped with 64GB of physical memory? Thanks, pwr
