Guys heres a little table to help you out to figure what time is best for what use.
Mon-Fri
8:30 - 18:00 : Surfing and e-mail is reasonably fast, downloads will be reasonable (no fast but reasonable)
Online gaming (local) and/or other non HTTP/FTP/SMTP applications range from slow to useless (P2P is useless)
18:00 - 00:00 : Surfing , e-mail speeds improve, downloads should improve as well.
Online gaming and/or other non HTTP/FTP/SMTP applications except P2P should range from good to exceptional. International gaming should be improved.
00:00 - 8:30 : All applications should be vastly improved including P2P applications
Weekend
8:30 - 00:00 : Surfing , e-mail speeds improve, downloads should improve as well.
Online gaming and/or other non HTTP/FTP/SMTP applications except P2P should range from good to exceptional. International gaming should be improved.
00:00 - 8:30 : All applications should be vastly improved including P2P applications.
Basically during business hours a LOT of network traffic is generated and this effects all applications , with ADSL and network shaping non HTTP/FTP/SMTP applications suffer the most.
This is not a conclusive table, but rather one I generated from years of internet use and experimenting lately with my ADSL connection.
