I have a cable modem, with download speeds approaching 4.5 MB/sec (as tested using http://www.speakeasy.net/speedtest
). This performance was measured using a Time Warner tech rep's laptop connected directly to the cable modem.
When my laptop is connected, however, performance is approximately 400 KB/sec (less than one-tenth that of the cable guy's). Nothing else is in the path (no network router, no extra cables, no docking station, etc.).
What can be negatively affecting my download performance? Upload performance is about as expected (approx. 300 KB/sec).
I'm not looking for a download manager... I'm looking for browser or registry settings that can positively impact my performance.
For example, the PC Pitstop website mentions the following registry settings that can affect performance:
Maximum Transfer Unit(MTU) The maximum packet size that is sent and received over the internet.
TCP Receiving Window Size The amount of data that is received before confirmation.
Default Time to Live The length of time the data is kept before being discarded.
Automatic MTU Detection Allows your system to identify the MTU size.
Blackhole Detection Checks if connected systems supports Automatic MTU discovery.
Large TCP Windows Support for larger amounts of data before confirmation of received.
Fast retransmission and recovery Allows for a fast transaction recovery after lost packets.
Selective Acknowledgements Allows for recovery without re-sending existing data after lost packets.
Number of Allowed Simultaneous HTTP Connections Number of open connections to a single web site at one time.
If any or all of these can have a big impact, what should such a setting be?
Are there possibly any IE security settings or other options that can have a big performance impact? Most of my settings are the default, by the way.
Setup Details: Dell Inspiron 600m; Broadcom 570x Gigabit LAN card; Windows XP SP2; McAfee VirusScan and Personal Firewall Plus; PGP; AIM Triton; MSN Messenger; Internet Explorer 6.029
If I disable/close all of my applications but IE, the performance remains the same. So I really suspect the issue has to do with the OS or the browser.
