Those apache benchmarks are far to good to be true. That's a bout a 17-fold increase, which has no resemblance to what I see in my job (with 60,000 apache servers in a mix of 32 and 64bit).

Well, did some scratching and the Betavine Vodafone Mobile Connect for 3G usb modems is available in 64bit also, so last night I decided I could not wait any longer and downloaded Ubuntu 64bit. Was way too late to start installing it though (2 in the morning *yawn*) so gonna do it today when I get home. Very very excited

I use both the 32 bit and 64 bit and honestly for day to day activities I havent noticed any difference. the only reason I got the 64 bit was for belnder 3d, which needed to access more than 3 gigs of memory when you start working with larger files.

Why are you trying to burst my bubble after I went and downloaded a 690meg image file? :-( I do a bit of video encoding, so 64bit should help a bit in that regard.

Well guys, my 64bit Ubuntu is installed and Flash is working (just followed the instructions when firefox told me it needed the extension).

Anyway, thanks for all your opinions and input.

Just encoded a DVD to AVI (divx) and took about 1 hour. On my 32bit setup it would easily take 2 - almost 3 hours. For me that is a mother or a improvement *grin*.

Jeez...you sure your PC/Laptop has enough memory to handle that work load?

If you can try 64 bits. It's more stable.

The big advantage of using a 64-bit OS is that if you've got more than 3GB RAM in your pc, the 64-bit version will pick it up correctly. The 32-bit version will "see" 3.4 GB RAM max.

Just installed Fedora 12 32-bit on a dual core with 4GB RAM on Friday and got 3.4GB RAM reported by the OS.

This is not entirely true.

A 32-bit CPU can address up 4GB of RAM but any hardware devices installed that have their own memory also need to fit into the same 4GB address space. This space used by hardware devices is generally placed at the end of the address space and any RAM in this area becomes inaccessible.

My guess is that on the machine you installed it has a graphics card or other devices using up the last 600MB of address space.

Also, it may be possible to enable PAE to allow more than 4GB of RAM to be used by mapping the physical RAM in and out of the 4GB address space as necessary.
