windows 7 also has IO priorities for processes

Interesting - I didn't know that (haven't used it).

Sorry - am working 12+ hours per day on CIYAM Open (and there is pretty no-one testing my software apart from myself either unfortunately - testers are in short supply around here).

can i help?

If you meant testing Dia's patch then he gave a link - if you meant with CIYAM Open then PM me to discuss.

BTW: I'm not saying that a checkbox to lower CPU priority (or even a default) is a bad idea - I just don't think it will help preventing freezes.

When I switch the process to low priority I get *no* freezes at all so yes I *do* very much think that it is CPU.

Sorry - am not going to grab a binary - as stated I have manually lowered the priority and found that it freezes much less (although Pieter is correct that it doesn't stop the freezing altogether which I guess is more the I/O side of things).

No tester - no patch, it's as easy as this Wink

That would be great and I'll happily use that on my old and dirty windows. Cheesy

As I already stated I have tested this on my laptop many times I am certain that it must be CPU and not I/O (it does not *freeze* when the task has been set to low priority).

Interesting - thanks for reporting, in that case.

You are free to take a look at my (untested and yet to be commented) pull-request.
It's perhaps just a starting point or could even be considered useless by other core devs, well see

After reading this thread I took a look at the same idea, to use some lower than normal priority. Perhaps I'll create a pull for this.

I'm quite sure your computer freezing up is not caused by the CPU needed for verifying signatures, but by the database I/O blocking your OS and other applications from accessing your hard disk. Scheduling the task at low priority will not help in that case.

The next release (0.8 ) should decrease I/O requirements a lot. If you're interested, feel free to try the test builds

Can you plese stop using that "Windoze" slang Wink

, thanks.

Oh sorry - didn't mean to offend - it's just that I'm not going to put a TM every time a type a bloody standard English word just because some American company things it has the right to *own* common English words and sue people who don't do this.

So let me know what I should call it (in a way the M$ is happy for me to with but with no TM or the like)?

Just use Windows Cheesy

, I call Linux Linux and Mac Mac, so that should be rather straight forward ^^.

Thanks

Unless that in the coming years there will still exists slow laptops or even those crap netbooks, I don't believe that this is necessary.

Um I would say that is an absolute GUARANTEE. Either underpowered hardware sold to meet price points accepted by the general public or otherwise decent hardware slowed to a crawl by software bloat. Ever seen the amount of services and background processed launched by third parties in the average user's (think your mom not anonymous hacker) computer after say 3-4 years.

IIRC the "move thread" is somewhere on the bottom of the page on the left.

Thanks!

I had actually never noticed that link was there before (wasn't trying to be lazy).

Finally moved to where it should have been originally posted (must be a bit tired today).

Can someone please explain "how do I move this topic"?

(actually maybe I'll just delete it as it looks as though it will take me more time to explain what the purpose of this topic is than I think I can be bothered with)

I'm sorry, I misunderstood your request.

The "move topic" is somewhere on the bottom of the page on the left, next to the "lock topic".
