64bit version??

[Rudy]

i use Winxp 64 and i was wondering you there's any plan for a 64 bit version??

Why would you need a 64bit version ?

Just because you have a 64bit CPUOS doesnt mean it actually gives any benefit to a bittorrent client.

I'm sure you can run the 32bit version on your system regardless.

I can attest that it works perfectly fine on x64, as that's what I'm running. However, when uTorrent reaches a mature stage when all the known bugs are fixed and all the intended features have been added it wouldn't be a bad thing to have a 64-bit version made, just to have it run native in the 64-bit environment. It's not really a necessity at all, it's more a matter of "cool factor."

[Rudy]

it works fine but it would be better to have a native version (just like most people wouldnt want to run a 16bit app on a 32bit OS....well maybe not quite as bad but you get the idea)

Its a know fact, at the moment, that when you upgrade to 64 bit, you will have to deal with 32 bit apps. There is no reason to expect all developers to create programs for a relatively new technology that is used by a small minority of users.

Of course, it'd still be nice to see it. As long as making a 64-bit version wouldn't require too much additional effort of course, I'm not advocating spending loads of time on recoding stuff just for the sake of us few who do have 64-bit systems.

[oxymoron]

Besides (correct me if I'm wrong), 64bit apps tend to be bigger than 32bit apps.

(I guess this has something to do with 64bit command prefixes and 64bit data types, but I'm not really a programmer^^)

You may be right. The 64-bit version of IE is a whopping 2k bigger than its 32-bit counterpart. I wish I still had the Riddick game installed so I could compare an app that actually uses resources. One app isn't really enough to devise a blanket statement. Guess we'll have to wait for more 64-bit apps to show up. Still, judging by IE, I'd say that a 64-bit uTorrent would be slightly bigger, but not enough to gripe about. I'm sure quality of code, language and compression would somehow factor in, too, and IE was made by MS, so.... who knows, maybe it'd actually be smaller?

The x64 processor has a larger number of registers, which helps speed because the processor doesn't have to go out to cache or RAM as often. Most of the time for this program is probably spent in the TCP stack, so I doubt there would be a significant speedup in this case (except maybe for hashing). Even so, the coolness factor can't be overlooked

The coolness factor can be overlooked =P

[Undesirable]

It could be overlooked, but that wouldn't be as cool.

Correction, the AMD64 specification basically has those additional registers specifically for the 64-bit extension of the current 32bit IA32 register set. There's no register that makes app go faster.

The extension registers are for memory addressing and mathematical calculations in 64bit mode. uTorrent isn't likely to require this unless there's something requiring more than 64bit of memory addressing (look up large databases and computing systems). It'd be nice to have... but then the devs would need a 64bit compiler, a 64bit OS, a 64bit coding app, a X86-64 compatible machine, and of course 64bit version of Windows. I'm sure some of you who run XP64 can help test but I don't think we're at the stage where they can freely test this on a larger scale.

I don't see what's cooler about a 64-bit application over a 32-bit application. What you should say is that the 32-bit µTorrent is cool since it can do enough things without needing any extra registers ;P

I'd love to see a 64bit version that supports more than 2 GByte of cache. Of course, the standard DSL user might not profit from that much cache (and does not have enough memory to profit from 64bit).

[Nostromov]

Why would you need a 64bit version ?

We can ask the developers now..
