Hi everybody, This is My First Python(tm), so please be kind! Attached you should find a patch to cache the PDE values during IA32 address translation. The resulting speed-up is modest but noteworthy. I've only enabled caching for non-PAE systems, but it should be easy enough to copy over to PAE systems as well. What do you think? As a bonus, this code also includes some endian-neutrality-changes (if there is such a word) to make the code work better on my Mac. Hopefully it won't screw up anything else. Please let me know what you think! cheers, -- Jesse research(a)jessekornblum.com
