Background info, this PC started life as an AT&T 363TPC Pentium 75, with 8MB Ram, NO external cache, and the Windows 95 Upgrade. It was then upgraded to 16MB Ram.
Then I upgraded to 32MB Ram and a Pentium 120MHZ(133 chip but strapped to 120) Processor. I did my first benchmark test at that time. Using SiSoft Sandra Standard for Windows. Here are the results:
CPU: 139 MIPS, FPU: 52 MFLOPS
Then I upgraded with 256K External Cache. I did the benchmark again. I did not write down the FPU resluts but the CPU went up to 177 MIPS.
I then found the proper switch settings to run the PC at the full 133MHZ speed. Now:
CPU 201 MIPS, FPU: 63 MFLOPS
I then "tweaked" the system settings and ran the benchmark again:
CPU 242 MIPS, FPU: 73 MFLOPS
I then upgraded to a Zerus 266 MMX Extreme.
CPU 426 MIPS, FPU: 90 MFLOPS
I have now reformated the hard drive to FAT32 and installed Windows 95B. (Before I had Windows 95 Upgrade from 3.1)
CPU 480 MIPS, FPU: 159 MFLOPS
Finally, I did something to improve the MFLOPS. Now my question, where else can I look in my system to make improvements on the FPU benchmark?
