copied!<p>I found <a href="http://code.google.com/p/urllib3/" rel="nofollow">urllib3</a> and it claims to reuse exisiting TCP connection. </p> <p>As I already stated in a comment to the question I disagree with the claim, that this will not make a big difference: Because auf TCP <a href="http://en.wikipedia.org/wiki/Slow-start" rel="nofollow">Slow Start</a> Algorithm every newly created connection will be slow at first. So reusing the same TCP socket will make a difference if the data is big enoug. And I think for 100 the data will be between 10 and 100 MB.</p> <p>Here is a code sample from <a href="http://code.google.com/p/urllib3/source/browse/test/benchmark.py" rel="nofollow">http://code.google.com/p/urllib3/source/browse/test/benchmark.py</a></p> <pre><code>TO_DOWNLOAD = [ 'http://code.google.com/apis/apps/', 'http://code.google.com/apis/base/', 'http://code.google.com/apis/blogger/', 'http://code.google.com/apis/calendar/', 'http://code.google.com/apis/codesearch/', 'http://code.google.com/apis/contact/', 'http://code.google.com/apis/books/', 'http://code.google.com/apis/documents/', 'http://code.google.com/apis/finance/', 'http://code.google.com/apis/health/', 'http://code.google.com/apis/notebook/', 'http://code.google.com/apis/picasaweb/', 'http://code.google.com/apis/spreadsheets/', 'http://code.google.com/apis/webmastertools/', 'http://code.google.com/apis/youtube/', ] from urllib3 import HTTPConnectionPool import urllib pool = HTTPConnectionPool.from_url(url_list[0]) for url in url_list: r = pool.get_url(url) </code></pre>
