Does you ever read comments describing this setting ? I can do it for you : "measured in % of total physical RAM". I.e. any value not in range [0..100] is wrong by definition. Read firebird.log, it should contain error message: "Incorrect FileSystemCacheSize setting %d. Using default (30 percent)." If you really want to limit file system cache by 50% of avalable RAM - set FileSystemCacheSize value to 50 (and restart Firebird), no need to calc in bytes... Regards, Vlad
