I wish I had thought of the Nagle slow start algorithm earlier! I reran my various performance tests, and I can confirm that adding CURLOPT_TCP_NODELAY resolves the performance issue.
Is there any way curl could automatically detect when it would be appropriate to use this option by default? ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
