Dear Wiki user, You have subscribed to a wiki page or wiki category on "Httpcomponents Wiki" for change notification.
The following page has been changed by RolandWeber: http://wiki.apache.org/HttpComponents/HttpClient3vsHttpClient4vsHttpCore New page: = Client side HTTP performance benchmarks = '''BIG FAT DISCLAIMER''': These benchmarks are NOT based on any scientific methodology so the numbers are likely to be non-precise == HttpClient 3.x code == {{{ public static void main(String[] args) throws Exception { if (args.length < 2) { System.out.println("Usage: <target URI> <no of requests>");
