weighttp¶ About¶ weighttp (pronounced weighty) is a lightweight and small benchmarking tool for webservers. It was designed to be very fast and easy to use and only supports a tiny fraction of the HTTP protocol in order to be lean and simple. weighttp supports multithreading to make good use of modern CPUs with multiple cores as well as asynchronous i/o for concurrent requests within a single thre
A comparison of SPDY and HTTP performance - Microsoft Research
We compare the performance of SPDY and HTTP in a variety of setting using a controlled tested study. We rely in publically available software and run with mostly default configurations. It is not our aim to extract every last bit of performance out of either SPDY or HTTP. Rather, we are interested in understanding how various mechanisms used by the two protocols affect page load times. This report
zsync — Optimised rsync over HTTP
AbstractThis document describes the thinking behind zsync, a new file transfer program which implements efficient download of only the content of a file which is not already known to the receiver. zsync uses the rsync algorithm, but implemented on the client side, so that only one-off pre-calculations are required on the server, and no special server software or new protocol is required to use zsy

Android Developers Blog: Multithreading For Performance
[This post is by Gilles Debunne, an engineer in the Android group who loves to get multitasked. — Tim Bray] A good practice in creating responsive applications is to make sure your main UI thread does the minimum amount of work. Any potentially long task that may hang your application should be handled in a different thread. Typical examples of such tasks are network operations, which involve unpr

PATH_INFO decoding horrors
Indeed, adding RAW_PATH_INFO could be a good idea, I also think that changing the PATH_INFO meaning could be worse than living with that bug. "So adding RAW_PATH_INFO, or REQUEST_URI which is currently not in the spec, to be undecoded might make more sense." Probably a bad idea to duplicate that kind of information in the environment. I don't understand what's the big deal about specifying PATH_IN
