Używam Psiphon w Windows XP. Mam internet 100Mbps. Program jest darmowy, prosty w obsłudze i chyba nie ogranicza szybkości transferu, bo osiągam wartości rzędu 6-7 Mbps. Nie zawsze łączy się z serwerem o wybranej przeze mnie lokalizacji. Np. wybieram Belgia a łącze się Serwerem w Polsce. Jestem zadowolony.

For a free VPN, it's amazing! It's got the fastest speed I've seen in free VPN's. Being open-source is a plus, as many other free programs that are closed-source would perform unknown, questionable functions.

It unblocks websites which are blocked in china and the best part is it is free. Plus as far as i have seen there is no DNS leak. Sometimes it gives a very fast speed. Like my internet here is 50Mbps, using psiphon, not always but most of the time, i get 12 to 15 Mbps, which is good enough for me. Just you need to try with different available servers.
