It isn't that NBD swap isn't working, it is that the site you reference above really sucks. Unfortunately our Junior High art class was searching for art examples on the net the first week I deployed our thin client labs. They ran into sites like this non-stop and kept freezing all our clients. I used that site as an example for really demonstrating the pixmap problem. If you play with xrestop on the client you can see that it climbs much higher with the NBD Swap than without. But that site takes about 1.5GB to actually fully load, hence the reason for using it as a demonstration. I increased my clients to 512MB RAM and increased the NBD Swap from the default 32MB to 512MB, this gets us by on most sites. The X_RAMPERC hack kills the browser before filling the 1GB available, so sites like the one above still result in a crashed browser for me. The RAM usage climbs so fast that monitoring with xrestop will show the client freezing before all local RAM and NBD Swap is used, but this is only because xrestop doesn't refresh fast enough. If you log into Screen1 on your clients and run "free" before loading that site you should see all your RAM and Swap, then switch to Screen7 and load the referenced website, then quickly switch back to screen1 and keep running "free" over and over again. You should start to see your NBD Swap getting used before a hang. Again, non-gecko based browsers will handle sites like the one above without a problem. I wish I could get the Firefox guys to talk to the Opera guys and learn why this is. Hmm, maybe I should join an Opera list and point out their superiority, maybe they could shed some light on why this is.
