Over the last bunch of days, sometimes my blog has been very slow to access. I wasn’t sure what it was, though, so I started doing some testing, and it seems that the lethargy has been tracked down to incompatibility of javascript created items that I’ve been adding to my blog.

Of course, we all have a lot of javascript things on our blogs if we’re monetizing them. Adsense is a javascript program. Widget Bucks is a javascript program. Chitika is a javascript program. I’ve had Adsense almost forever, and my blog never ran this slow. I’m not sure about either Widget Bucks or Chitika. I had two other minor things on my blog, both from Grader.com, and I took those off because each one was a javascript program.

Not that talking about javascript slowing down blogs is new. A blog post that probably didn’t get the attention it deserved comes from Alex Iskold’s Technology blog, where he wrote a post titled How Javascript Is Slowing Down The Web. In it, he talks about the problems that can occur when multiple “single” lines of javascript code come together from varying sources. He talks about how javascript performs things sequentially and not concurrently, and that anytime a piece of JavaScript is being loaded or evaluated, everything else has to wait.

Now, supposedly there’s things that can be done for different browsers, but none of those things are absolutes. That, plus it’s very technical stuff; most of us regular folks won’t understand it, let alone what to do with it. However, something I’m speculating is that when there’s two javascript programs next to each other, that’s when things have an opportunity to fail, even if the same company created both programs. When I first removed the Widget Bucks affiliate banner that was sitting next to their skyboard banner, this blog was running much faster. Since then, though, it seems to go up and down. Frankly, I’m not really sure what to do next, other than removing all javascript programs, and that’s not about to happen. It’s possible that it’s related to either the LinkXL or Kontera ads that have recently started running on this blog also; I’m just not really sure.

Luckily, the slowdown time is infrequent, so I hope it doesn’t overly disturb anyone. However, if it starts bothering me often enough, I’m going to start moving things around some more, trying to make sure there’s some kind of distance between all the javascript that’s going on. At least the Daily Puppy widget isn’t javascript; aren’t they cute? Anyway, Chris Pirillo of Lockergnome talks about how javascript works in web browsers, so I’m sharing that here; enjoy!
