I don't believe tHttpd is threaded. http://www.acme.com/software/thttpd/notes.html on the section regarding non-blocking I/O: "The fourth generation. One process only. No non-portable threads/LWPs. Sends multiple files concurrently using non-blocking I/O, calling select()/poll()/kqueue() to tell which ones are ready for more data. Speed is excellent. Memory use is excellent. Portability is excellent. Examples of this generation: Spinner, Open Market, and thttpd. Perhaps Apache will switch to this method at some point. I really can't understand why they went with that complicated pre-forking stuff. Using non-blockijng I/O is just not that hard." > Cheers, > -Peter > -- > Peter Wemm - [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] > "All of this is for nothing if we don't go to the stars" - JMS/B5 > > > To Unsubscribe: send mail to [EMAIL PROTECTED] > with "unsubscribe freebsd-hackers" in the body of the message -- Dominic To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
