Yesterday, I made a post asking if anyone else had noticed LW being particularly slow. I offered to collect data on this, and was fairly sure (Probably about 80%) that it would show that LW loaded slower than other webpages. I took the post down after about 20 seconds (sorry if I confused you) since it was almost entirely insubstantial, and resolved to collect some actual data to report.
So I did that. Data was taken using this website. I was on my school's wireless network at the time, running Firefox 8.0. I didn't think to disable my addons before doing this, but I was running Adblock Plus, FastestFox, Greasemonkey, IE Tab 2, Movable Firefox Button, Omnibar, and Web of Trust. Data points were generated at the following websites. Each website was measured five times.
After doing this, I downloaded an offline copy of each of these websites, and calculated load time per byte of website size. I plotted these results. To my surprise, LessWrong ended up being one of the fastest, although PredictionBook could use some work. I considered deleting the obvious outlier, but trends are clear even with it in there, and all things equal, I'd rather not delete data. Data points (in groups of 5) correspond to the webpages above, in order, ie. the first five points are from the discussion page of LW.
Surprisingly, LW is still one of the best even when only raw load time is compared. But the discussion page (remember, that's the first 5 points) takes somewhat longer than the other pages:
The excel spreadsheet used to generate this can be viewed here.
Since there is no real problem here, and it was all in my head, I considered not publishing this, but after all of the discussion we have about positive bias, I wasn't about to turn around and do the same thing. So here they are: my negative results.
