Mousing over links seems to have slowed down a lot lately. To reproduce: 1. Mouse-over a list of links. You'll notice that the statusbar has a hard time updating with all the info. 2. Drag the cursor (as in selecting text) over a paragraph that has a link in it. When the cursor is above the link, the selection will "lag" before it continues... This is quite hard to explain. But by trying one of the two above testcases, you'll notice this regression. Build: 2001-11-23, Windows 98.

This is a bad and very visible performance regression. dbaron, any idea what the slowdown could be? Roc, is this due to your checkin(s)? (wild guess.)
Keywords: regression
Summary: Mousing over a link or dragging over a link is now extremely slow → Mousing over a link is now extremely slow (:hover is slow)
This is almost definitely due to roc's changes, which were causing things like :hover to repaint the entire page (before he backed them out).

This is still much slower than usual in today's CVS trunk. :-(

A good testcase: go to http://www.w3.org/TR/SVG/ and mouse fairly slowly over the list of links... You'll definitely notice the problem. The :hover effect will not be applied unless you stop moving for a little while.
Is it slower than it was in a build from a few weeks ago? (It seems pretty quick to me.)

Yes, it's much slower. I will download yet another nightly build and see if the problem is reproducible there.

It was confusing that the nightly the day _after_ roc had been backed out was still showing the slow, bad behaviour. In this new nightly I just downloaded, things are back to normal. Phew!
