This is a followup to my post about Measuring Development Speed. Here’s an updated graph showing the current state of head/master:

Most dramatic change in Struts/jsp LOC is now: 5412 (time period ending Feb 2011)
Most dramatic change in SpringMVC/ftl LOC is still: 3665 (time period ending Sep 2010)
Again, some assumptions/disclaimers:
- these data are not useful for estimating speed of future refactoring work
- all acceptance tests pass in refactored areas
- look & feel of refactored areas is acceptable
Also see this this thread on the dev list about the usefulness of these measurements.
