Hi, We had serious performance degradation once we switched our clients to 64 bit machine. After a thorough investigation I saw that the default file access mode determined for the 64 bit is memory mapped files. When I switched to direct access mode it flied out of the roof!!! (350 times faster). I have here 3 important questions: 1. Why is that ? 2. Is it safe to use the direct access mode instead of the memory mapped files ? 3. I Couldn't find a good documentation on this, can you please explain the functionality of each mode ?
Thanks, Nadav
