I decided ubuntu is going to be an adventure/difficult as is. No need to make it more confusing.

Running Vista x64 though.
 
I'm running Fedora 9 (64bit) on my notebook:)
Always have been a fan :)

I installed Hardy 64-bit originally, but realised that I would have to redownload all my cached deb files again. So I downloaded 32-bit and went on with my life. 64-bit does have some compatibility issues however, so it wasn't exactly too hard a choice for me anyways.
 
Just read the pdf document. Yeah it is old (I can't remember my pc being that slow) but is relative when it comes to percentages. When 64-bit compatibility is better I will glady run a 64-bit OS on my Core2Duo and give it the ability it so desperately needs.
 
I suspect by the end of today the only 32-bit OS I will be running is XP. Debian, Sidux and Fedora 8 will be 64-bit.

EDIT: In fact I can now confirm that I will be removing my Debian 32-bit install.

I wonder how long it takes till we get true x64 instead of this mixed hybrid 32_64 they have now.

I dunno, but I'm scared we'll be having Intels starting to take off from the table at the speeds they will achieve :D

Would be nice. Your desktop can double as a remote control aircraft... :D
 
I can see a speed boost when running 64bit but not that much. Maybe I need to put the PC through its paces first.
 
Depending on the nature of the application, you should see a huge difference in speed. But obviously some programs will not really run faster. It also depends on the programming differences between the 32-bit version and the 64-bit version. Not going to throw in any more technical stuff.
 
My 64bit Kubuntu works slower than my Vista 64bit. According to Ksysguard, it nearly uses my full 2gb ram, while vista rarely goes above 1gb. Any thoughts?
 
On my debian 64-bit install with TVTime and amarok running (FF3 RC1 as well) it shows application usage of less than 512MB. Though it does show that the full 1GB is being used what with cached and buffered memory.

It makes more sense to read from memory cache than to reread from disk. Memory I/O is way faster than hard drive I/O.

I started running 64 bit (Slamd64) alongside 32 bit (Slackware) about 3 years ago. Over the last year I've pretty much completely switched to 64 bit. 32 bit stuff like Skype, Cedega and CrossOver runs fine with the necessary 32 bit libraries that came with my distro. I had to add two 32 bit libraries for Skype 2.0.0.68.
 
maybe as far back as 12 to 18 months ago 64-bit was a pain. Though there might be some things that require extra steps as compared to 32-bit counterparts, running 64-bit is 95%-99% flawless.

Or maybe since I bit the bullet around November last year I have becoming used to dealing with 64-bit issues on whichever distro I install.

You have to be doing something wrong. My installation rarely goes above ~500MB even with several applications open. Never used up even close to all my RAM in a very long time.

Go to processes in KSysguard and sort according to RAM usage. Then you can see what's using all the RAM.
 
froot - see post #16. Maybe swift-wp should upload a snapshot of ksysguard cause if it is anything like mine the actual apps are using less than 512MB although all of the RAM is being utilised.
