| Nov 7, 2014 at 5:46 | comment | added | Jamie Hanrahan | PAE was not "removed in Windows 7 because it is no longer needed", it is still present in Windows 7 x86 - it's just there by default rather than having to be optioned in. | |
| Nov 7, 2014 at 5:46 | comment | added | Jamie Hanrahan | THat's a myth. The overhead due to PAE is tiny. And if you dislike PAE you should really hate x64, because the page table structure on x64 looks just like PAE, just with yet another table level added on top and more bits for PFNs in the PxE's. | |
| Aug 30, 2013 at 8:39 | comment | added | phuclv | search for 32-bit vs PAE performance benchmarks and you'll see that PAE is not a good solution. phoronix.com/… | |
| Feb 23, 2013 at 1:42 | comment | added | vonbrand | PAE requires page table switcheroo to work, and that is costly in terms of performance. | |
| Feb 23, 2013 at 0:29 | comment | added | Hennes | @series0ne PEA also applied to win XP 32 bit, so not only server OS'ses. It got removed in windows 7 (and maybe already in vista) because it no longer is needed. 64 bit CPUs have been in use since ~1979 and they are now that common that it is safe to assume every newly installed computer has one and thus the X64 version can be used with much less hassle. | |

| Feb 22, 2013 at 22:23 | comment | added | 0xC0000022L | @series0ne: this is a licensing issue. Scott even mentions this in his answer. | |

| Feb 22, 2013 at 22:09 | comment | added | Matthew Layton | Ah I've heard of PAE before but never investigated it. It appears to be largely used in server architecture, so does not seem to apply to a Windows 7 32bit installation, as the list specifies that W7x86 only allows up to 4GB | |
