Checkout the FileSystemCacheThreshold configuration parameter in firebird.conf. Set it to 0 and also use a small page buffers value. Another area of RAM usage is for temporary data used by grouping, sorting etc. If you also want to (almost) disable that area, watch out the TempCacheLimit configuration parameter in firebird.conf. -- With regards, Thomas Steinmaurer http://www.upscene.com/ Professional Tools and Services for Firebird FB TraceManager, IB LogManager, Database Health Check, Tuning etc.
