Bitcoin x64 for Windows

[ichi]

Wow, that tweaked one... I'm getting stunning rates.  I have a quad core Intel laptop.

I have ... one while everything but bitcoin (including explorer.exe) is shut down.

	Stock:	x64 v1	x64 v2	x64 v2 Tweaked
<snip>
Optimized Usage:	1500-1800	2000-2500	1500-2000	2700-3400

On a Quad-Core AMD Opteron 2376 server running Ubuntu 10.04 Desktop x64 (wubi) and Bitcoin 0.3.0 x64, I get ~2,200 khash/s.  With Bitcoin 0.3.0 x86, I get ~2,000 khash/s.  What would I expect running Windows Server 2008 x64 and Olipro's x64 v2 Tweaked?

Is it faster than the stock Linux x64 build?  Could the Linux build be similarly tweaked?

[Quantumplation]

Ichi: Probably pretty fast, I saw a huge increase in performance to the tweaked version.  No tellin until you try it though.

I'll give this one a run, the last build would crash randomly after a few hours  

same here,
MSVC build didnt work at all (missing DLL even after vcredist_x64 install),
Intel build seems to work fine for 1-2hours and then crashes.

I get around 1600 with the regular client, Intel build ~2150, latest Intel tweaked ~2220.

Update: this one seems to crash even faster, 30minutes first run, almost 1hour second run

the missing DLL is in my first release (libeay32.dll)

Vista x64 here

From regular version ~1700khash/s to this version ~2300khash/s (last versios posted here)

Really nice, but i think need to be more stable

given that it's based on stock code and I doubt there's an issue with the compiler, it's more likely there's a bug in the SVN source, I'll make a build from the last stable production version just as soon as I've finished this CUDA code off.

thats not the one causing MSVC build not to work, that'd be MSVCR100.dll.
anyway, the Intel build does work, although it crashes. 

keep coding, i'm looking forward to test a cuda-version on my gtx260.

My experience is similar, the first release was rock solid like the original client, the other releases, while still faster, randomly crash after minutes/hours/days  so it's kind of random.

So it's a trade off between stability and speed. The faster it gets, the less stable it seems. 

Of course, I have mine on a batch to restart if there is a crash and to count how many times the program crashed during the day for example. So far up to about 2 crashes a day.

There is a speedup for me, but it is not faster than the ubuntu 64-bit version. I am surprised; with SSE2 I expected it to fly :S

Yeah, my Linux 64bit systems still have the leg up on my windows servers, even with this optimization that is made that speeds them up by 50%, seems Linux still rules the roost for coin generation speed.

Most of my coin generation comes from my Linux servers more than my windows servers, it's about a 1 to 4 ratio, for every 4 blocks made by my Linux servers, 1 will be made by one of the windows servers.

that's not an indicator of performance mind, block generation is pure luck, it's the hashes per second that mean something.

Yes, sorry, I left that part out, the Linux servers (same hardware) always generate higher khash/s than the windows machines, at least mine do. Your mileage may vary.

On my desktop, I have a dual boot between Ubuntu and Windows 7. The SSE2 build brings Windows 7 speeds up to around the same as the Ubuntu build.

OK.  Could someone please explain the why of that, in terms that a non-programmer can understand?  Why is the stock Windows build slower than the stock Ubuntu build?

Optimizations mainly. When the program is being compiled on Windows, certainly optimizations make the program more efficient.

On Linux, we have both 32bit and 64bit builds to take advantage of the 64bit arch of the system. On windows, there was only a 32bit build.

Thank you.  I'm glad that I'm moving to Ubuntu.

I still prefer windows 7 for many things, but I am liking Ubuntu more and more. If only some things weren't such a pain in the ass to use (Tor: Windows 7? 1 minute install. Ubuntu? WTF...)

[ichi]

I really like Windows Server 2008, which is pretty close to Windows 7.  It'll be a while before I give that up.

OTOH, I'm thinking very seriously re going with Ubuntu for my next primary desktop.  As a test, I've recently installed Ubuntu 10.04 Server x64 + GNOME on an old Core 2 Quad machine.  Everything except boot lives on an encrypted RAID5 array managed by LVM.  Losing Excel 2007 might be a problem, though.

Although I don't use Tor, I'm sure that there must be many setup guides for Ubuntu.

This is way off topic.  Sorry.

[Quantumplation]

I absolutely hate Ubuntu, mostly because of the community surrounding it.  I much prefer gentoo, Debian, etc.

[andy_3_913]

mind if i ask?
satoshi has released a couple of updates recently, mostly about security concerns as far as i can see.
how are the 64bit versions keeping up with these developments?
