This case eliminates disc problems and allow to highlight other ones. In other words RAM simulates the very good system IO like a PCIe-SSD. > The comparision can show some problems but results must be analysed carefully. The real tuning exactly must take into account all layers including disk IO. -- Roman Simakov Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
