Great Review of Web App Speed

Recently came across Drew Crawford's article on the speed of web apps, what affects it, the reasons for that and finally some quanitative analysis. This is a must read.

Make Windows use a realtime clock

First off: Markus Kuhn's classic rant about windows storing the time in local time instead of UTC and why it's dangerous and downright moronic.

Solution:
Create a DWord called RealTimeIsUniversal under

HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation

and set it to 1.
Beware that there are issues which Markus Kuhn details and that you should be aware of.
