Re: blindness and overclocking

And if you did, you would discover that it doesn't help you at all, I'm pretty sure. You only get 10-20% at most, *especially* if it's a dual core machine that's bad enough to lag out the screen reader. Those impressive overclocking results that have you and everyone else on this thread going "wow! Must do that!", they come from buying the high-end gaming processors from intel that Intel designed to be overclocked, motherboards designed to be overclocked, cooling systems specifically marketed at the "gamer" with tons of things about how they're massively overpowered because the companies behind them know who they're selling to. In fact modern processors specifically come in unlocked variants that you have to get if you really want to do this. By the time you have that I promise your screen reader isn't laggy anymore.
You don't buy a cheap computer and overclock it and now you have a good computer. You buy a cheap computer and overclock it and barely get anything plus it was a cheap computer that couldn't handle being overclocked and a year from now you replace it and end up spending more than if you had just got a better computer in the first place.
There isn't some conspiracy by Intel or something where they give you processors that are intentionally running below where they can safely run but you can overclock them because Intel is out to make you give them money. That's not how this works. When you start overclocking you're making trade-offs. Yes, there are safeties and things these days, and if you stay within them you might be okay. But those impressive overclocking results? They usually turned off said safeties, as well.
but how screen readers actually lag is IPC gone wrong. The only thing that can really help with that is more cores and memory, not faster ones. You can't overclock the hard disk, and what usually ends up happening on low-end machines is that background apps end up swapped out and having to swap back in all the time every time they wake up to do work, plus foreground apps being partially swapped out to disk as well. That's all blocking operations that overclocking can't do anything about either. Basically screen readers are as slow or slower than whatever apps they monitor.
At the end of the day, yes, hypothetical-you probably can't afford a great computer. But trying to get the cheap one and overclock it to make up for that, that's just not how this goes. Overclocking is a hobby for people with more money than sense, not for people who are trying to stretch a $500 laptop to be a $1000 laptop.
