64-bit == faster de/compression;

It speeds things up for those of us running x64.
Also dual-core support would be good, if it’s not already present.

Multicore support - from 2x to 8x faster than WinZip 12
Support for dual core, quad core and i7 computers for nearly up to 8x speed improvement over competing utilities that do not have multicore zip support (WinZip, WinRar). Multicore compression is supported for deflate and LZMA methods.

I just put together a new Vista 64 machine with a quad core AMD processor so I should see a dramatic improvement over my old XP powered single core AMD?

because of 64bit - no… because of quad core, yes… when it comes to zip (deflate/lzma) and 7zip compression.

Particulary, zip deflate is blazing now :-). Of course, with PA 2010.

Thank you!
