I've been using the aforementioned web accelerator - which I think seems pretty useful. Heard it first on BetaNews. I've been using it for about half an hour or so, and pages do seem to load faster, but that might just be a placebo effect. The best thing though is that I can surf with it and Opera still ad-free through Proxomitron, all you have to do is put the proxy info they give into Proxo's proxy and check "use remote proxy". Voila - ad-free sped up smurfing.
What I realised later when I finally wrestled MS Anti-spyware into submission (I had paranoid-ly stopped the toolbars from installing), what the fantastic secret was behind google's cunning plan. Because they have a counter for how much time saved I could see the moment when time saved was being racked up - and guess what - it's when the ads are loaded. Google is saving you time by loading the ads you don't want faster.
To be fair this is not an inconsiderable service - people who don't use ad-blocking like Proxo will probably have a much improved browsing experience, since ads are becoming more and more the cause of web pages loading slowly - either due to lags on the ad server, or the size of the graphical ads in relation to the page content.
So basically when I went to check my stats, I realised that the time I spent with Opera didn't show any time saved. I can only assume time was saved because it felt faster and google news loaded and reloaded in a flash - which is what I assume prefetching is for. So either it's all placebo and it's crap, or it doesn't log time saved for "other browsers", or it's just a way for Google to collect stats and help advertisers serve ads faster. Because really, the content of the page would load, then the ads would flicker on a second later, just as the "time saved" would tick over.
Ah ok, I'm seeing how it works now, it does indeed prefetch links - for instance they use styling to extra underline prefetched links - for instance the english wikipedia front page when I was on wikipedia.org. Though I think they do it in the time you're supposedly "reading" the page. I'm not sure if this works properly in Opera, since, I haven't seen the styling links flicker on. I'm sure cleverer people than me will talk about this eventually, but at the moment, it's useful, but funny. Really, it might just be my 25 Mbit connection kicking in.
Oh my, I just realised the WikiNews page that they loaded on IE was from 5 days back - silly buggers. But Google News loads faster, which is one thing - and accessing Google's cache instead of the wider InterWeb is probably that bit more efficient. There's probably some form of compression going on as well, I'd suspect. It's interesting that because of the pre-fetching, Google says this is meant mostly for Broadband users. Pre-fetched links still not showing up in Opera, might try turning on FF's CSS ad blocking and see how that affects on the landscape.
Well I'm not wrong - the counter doesn't seem to tick up when browsing with CSS blocking - even with the prefetch pages, which is odd. Well, ok, not *not* tick up, but tick up in increments of .1 and .2 of a second. So really it is just about speeding up ads. Or not, since I'm getting the feeling all of this is just me talking out my ass - in IE it does appear to tick up the same with the ads. I don't know, it might just be google's caching being efficient, and the ads do seem to take a second to load - though not as long a second as I remember - but then again I haven't seen ads for ages.
It does a great job prefetching my bog though, especially if you're going post by post - though then the prefetch underlines start to get particularly annoying.
I think my final verdict is gonna have to be to try it, why not - though the ticking up can get a bit obsessive, so you might want to turn that, and the pre-fetch underlines (eventually) off.
I enjoyed your article, however I do not use proximation and my counter still does not move. I think that this is because of my Opera use. Once I ran Firefox, I started saving many milliseconds.
