I tried a RAMDisk on Windows. I haven't tried at home on Linux. I'm not sure if I tried the C API to RAMDisk database combination, only the Tcl API to RAMDisk database combination. Maybe Tcl was the bottleneck here. > Is that a burst rate or a sustained data rate? You need to achieve > about 70k rows per second to be able to maintain 66k rps. Well, at the moment it is mostly only bursts of data, but I have no control over the possibility that it will become even faster, or continuous, so I want need to push the envelope. > Maximum TPS is 60 on a 7200 rpm drive.

At the moment I'm not sure what HD is installed on the vehicle where the data is produced, but it can always be improved upon by throwing $$ at it ;-) Cheers, James. ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] -----------------------------------------------------------------------------
