I had just tryed Mma & Win 95, Mma & Addtwo, and a enhanced priority for the kernel. The detailed results follow later. It seems strange to me tha an additional load of the system increases the speed of the kernel. The best reults I had obtained, where with setting the process priority of the kernel from NORMAL to HIGH. This speeds up the calculations at least by a factor 2 or 3. Here the solution get the file unix95.zip (from ftp.cica.indiana.edu:/pub/pc/win95/sysutil) beside many othe use full tools there is a unix-like ps.exe and a unix-like nice.exe. When the kernel is launched get the process ID of the kernel and set the priority with the nice command to HIGH. The system is still usable. MS-DOS windows where a bit slow but the frontend still works fine, all calculations where 2 or 3 times faster than before. Is any one in the group who is familiar with Windows NT programming? How to obtain the process ID or handle of all running threads? A small MathLink programm that switch the priority of the kernel will do all things well -- I suppose. Or better a MathLink program that increases the priority of the kernel when a input is evaluated and decreases the kernel priority when the kernel does nothing. Jens
