Actually you can use connection keep-alive without tossing Privoxy. Just put Polipo between Privoxy and Tor (be aware that using another proxy behind Privoxy will render some of Privoxy's actions useless, though). My impression is that keep-alive (in the setup described above, and without Privoxy in the chain) doesn't buy you enough to be noticeable. Of course adding Polipo to the proxy chain has other advantages, I didn't do any scientific benchmarks either, and I may be biased. I used Privoxy's CVS version to measure the effects of not having to use prevent-compression for filtering, though: fk@TP51 ~ $head -n 15000 /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | grep Decomp | privoxy-log-parser 16:50:26.413 0815c700 Re-Filter: Decompression successful.

Old size: 7351, new size: 36324. (saved: 79.76%) As receiving compressed content seldom saves less than 50%, I assume that for Privoxy 3.0.6 (chained with Tor) the missing zlib support is a much bigger slow-down factor than the missing support for connection keep-alive (if that's a slow-down factor at all).
