Any speed up on 64-bit or 2+ core systems ?
A question to those, who have 64-bit or 2,3.. core CPU - is there any speed up in common PC performance? How many "bogomips" at dmesg output ?
|
Probably not.
I don't use a lot of "common" software, but web browsing, video all looks the same on my i7. I'm expecting kernel compiles to be a different matter. Might even go back to gentoo ... |
I have single and dual core 64-bit systems. I cannot visually see any difference in the performance of either. I'm not an avid gamer and the most resource intensive application I use is the Flight Gear simulator. Can see no differences in performance. I think any improvements here would require a better graphics adapter.
In the area of stats, I really have no basis for comparison since I have different CPUs with differing clock speeds. The only things in common are the software, memory, and graphics adapter. Cheers, Lou |

I'm testing Slackware13-32bit parallel with Slack12-32 on the same PC now (rather old PC). Common performance of out-of-a-box Slack13 kernel is lower then my custom kernel for Slack12 with some system tuning. So, I'll create custom kernel for Slack13, by no means. And what about 64-bit and multicore systems? Any performance boost? For 3D rendering in example (using Blender)? |
It's me again.
I forgot to point out that on my dual core system I've built my own kernel tailored to my AMD Athlon 64 and my system hardware. Still see no differences. Lou |
Well, I dunno about you people, but I definitely DO notice a difference, especially with some programs like encoding, encrypting, games, etc.
App start times also are a bit faster. Test it yourselves, run 'time' to time commands as they run. I do compile my own kernel. |

It's a new toy for now, but I'll get to do some serious processing soon. |

Danzille,
Thanks for the thanks. Like you, I'm fairly new to LQ but I think the Thanks are supposed to be reserved for cases where someone has helped you solve a problem. In this case, I think responding Yes to the Did you find this post helpful? would be more appropriate. I'll know soon enough if a moderator jumps in. Cheers, Lou |
I compile my own kernels for use on my x64x2 machine. I also tend to compile a lot of programs using slackbuilds.org. The difference in compile times is tremendous when taking advantage of both cores. I can only imagine what the 8 core processors are like in this regard.
|
I have a Core2Duo quad core, and I notice a huge difference in compile times. On one of my single core machines, kernel builds would take forever, now they take about 15 min or so.
|
I have a core2duo e6600 system (dual core) and an i7 920 system (quad core with hyperthreading) both do/have dual booted with slack13 and slack64-current. They both have 6GB RAM and comparable Nvidia cards.
I didn't notice a huge difference when I built the i7 system, but after I used that exclusively for a month, then fired up the core2duo I was shocked at how SLOW it felt. For building kernels and packages there is NO COMPARISON the i7 does in 4-5 minutes what the dual core core2duo did in 20-30. Of course that's using Code:
make -j11 One thing that makes my results a little less meaningful though is that I overclocked the i7 to 3333MHz whereas I left the e6600 at the stock 2.4GHz. |

It depends a lot on the size of the kernel, so that's not a good benchmark, try firefox instead, the size is more constant.
