I just upgraded my laptop (nothing special, dual core, 4GB RAm) from Vista 32-bit to Windows 7 64-Bit. I also swapped the factory HD for a Seagate XT 'hybrid' drive. I'm curious if this will result in any shorter crunch times?

The upgrades had nothing to do with crunching, but I'm curious if anyone thinks it will make a difference or if it is 100% on the processor and I will not see anything.

You shouldnt see any difference. The apps arent much different from 32 to 64 bit OSes and 7 is like the unbroken Vista.

Use 64-bit optimized applications for CPU, they are noticeably faster than their 32-bit counterparts, like 10-15% faster.

Yes they are faster than stock apps, but keep an eye in the temperature, specialy on a laptop/notebook.

Thanks for the tip, will give that a shot later....and I have it set to only use 50% on all the laptops I have it installed on to keep the temps down.

Generally the storage media for BOINC & tasks is irreverent. There could be some benefit to faster storage, but it may be so small no one has been able to measure it.

A default install of 7 has a few less things running in the background than Vista. So that may actually help a bit. If your Vista installation was the factory install with all of their "stuff" installed and running that may be prove to be a more significant gain.

Some applications run twice as fast (100% faster or at 200% normal rate depending on how you like your percentages!). Notably various prime searches.


But why oh why are people still lingering in 32bits on 64bit hardware?! There's a lot of transistors and expense to give you the extra performance and functionality of the 64bits...


Happy fast crunchin',

I distinctly specified which applications and how faster they perform. For his systems, only Intel CPUs.
Ppl use 32-bit OS, bcs most of them are more pragmatic than exotic and adventurous. Perhaps some of them wonder why me or you are still using same vacuum cleaner for last 10 years. Answer is same for both questions - bcs it fulfills its purposes.
