Following are a few tweaks you might consider:
1. Put the page file on a separate (fastest) HDD (not separate partition on the same HDD). Why? Seek time is a bottleneck; if data files and the page file are on different HDDs, the heads are not going back-and-forth between the two on the same HDD;
2. Defragment putting your most important files (and the page file on its separate disk) at the beginning of the disk. (Windows, by default, puts itself before anything else, including the page file, at the beginning of the disk);
3. Since you have plenty of RAM, set your page file size to one-half your RAM but set the max to approximately 3 times your amount of RAM.
