Big impact from reducing page weight and load times

Another holiday project for me was to work on reducing the load time for my pages. There were a few reasons for this:

1. I was using bandwidth like it was going out of fashion and finally was about to violate my (very generous) limits
2. My pages were taking a ridiculous time to load and it was just embarrassing
3. Google have very publically been stating that page speed is important for ranking (and the whole web has focussed on this in 2010)

As such I used my webalizer log file analytics package to pull out the highest bandwidth files and I isolated that the moo tools js (I was using for some super simple text animation) and a promotion banner were using 40% of the bandwidth. Although this is stating the obvious usually 90% of the actual impact of the problem you are dealing with is driven by 10% of the problems. Webalizer is a great way (on bandwidth usage) of homing in on the causes. I did about 2hrs of work to hack everything around and reduced my bandwidth usage by 25%. The surprise for me was that I saw an immediate impact on my data:

All year my pages per visitor has been down substantially. Users were getting bored and leaving the site faster. Reducing the page weight by 40% increased my page views per visitor by 25%. What was really interesting about this is that it stood out in all my data. For example even though I should have cut total bandwidth usage by 40% it only went down 25% since the number of pages being downloaded from the site spiked substantially. This was awesome to see :)

Wow... never thought it'd make such a dramatic difference. Have you seen an uplift in referral traffic from Google too? And what about visitor loyalty (repeat visits)?
