At least the Java byte code is very specific to Java; it doesn't map well into other languages and specifically not well into dynamically typed languages like Perl and Python.
In CVS there's already a mini language (Jako) that can be compiled into Parrot assembler code.

I don't think there is any major ad serving companies that do not allow the client and proxies on the way to cache the actual image. That would be stupid and a needless waste of bandwidth for everyone.:-)
The redirect (less than 1KB) is never cached though (except on broken clients).

Uhmn too many wrongs on so few lines to just ignore.
1) Try to do the numbers and you'll find that the ad companies are doing customized and optimized and very much "asynchronous logging". You don't serve many thousand ads per second from one server (so you need to gather the "logs" to a central server for that), and you certainly don't do a diskwrite for each hit (and especially not a syncronous one).
2) The "weblogs" are very useful. How else would you pay the host sites and charge the advertisers for the traffic?:-)
3) The initial "hit" will not be cached, no. But the actual banner content (typically the ~10k.gif) will be cached as any other normal static image.
if the ad company should sell text ads they would probably want to serve them (via some javascript / iframe stuff) and then they would slow down the site (slightly).
The very short DNS ttl their load distributer uses gives extra DNS lookups / more latency. And it doesn't always do a very good job at finding a close server anyway.
ValueClick are btw serving banners very fast and very reliable these days.:-) (I work there so I know, but I can't quote any numbers).

On FreeBSD I imagine?
Try the latest version from CVS, it should work now.

you can also access the cvs repository.

.pbc (parrot byte code) files through Apache. I got distracted though, so I didn't finish (yet).
I started on making a mod_parrot so that you can run

It's almost scary what they have on file.

For serving ads Akamai is not always that great.
