Re: [firebird-support] Firebird configuration for better performance
Change your fb to Classic or Superclassic so you can use all cpu cores. If you choose Classic you also need to increase hashmemslots by 10 times at least (prime number). Google for it.

The database is a small database used for inventory and stock control with about 30 tables, with about 6 - 8 concurrent users, and relatively moderate workload (INSERTS, UPDATES and SELECTS) throughout the day. The database is currently empty (we're just starting out) and the size currently stands at about 6 MB and is due to grow as data and transactions are added.

If not what are the ideal values I should adjust to? Thanks in advance for any enlightenment. Regards, Steve Faleiro

Hi Steve, This database is very small, you should not have any performance problems (except related with lack of indices or bad design of metadata). Usually we recommend to set 1 buffers for SuperServer - our experiments have shown that 1 is the best # of buffers for SuperServer.
