I am on Windows, so I have enabled EnablePMTUBHDetect parameter instead, as per http://support.microsoft.com/kb/314053 It have helped somewhat -- now instead of waiting for the full page, half of the page is downloaded, and then the waiting starts. I am not a TCP expert, so have no idea what may cause this. -- Alexander S.
