Hi all,

Purgatory seems the only adequate place for this note.

During the last 2 evenings, I managed to dramatically improve the download speed with my new 3000 Kbit/sec ADSL line. Such tweakings are particularly effective with high-speed and high latency transfers.

latency <=> round trip ping time, typically 50 -250 [ms], depending on the distance and the number of hops to the server.

I did the optimizations both for my XP laptop and my Linux machines that are all part of my switched & routed intranet.

So if anyone is interested what can be done, let me know. I am talking about factors of two for my ADSL 3000 line. In case of my superfast Gigabit office LAN I gained a speed factor of about 10!!

Im on 512, would I see any benefits?

I am afraid with 512 Kbits/sec the effect of tuning is rather minor...

If you have Windows you should download the small tool 'DrTCP' and make sure that your TCP/IP receive window size is at least 32K which is the default with Windows XP. But you forgot to tell me your OS. Things are strongly OS dependent, however...

im on the usual Windows XP Home. Ill try DrTCP when I get my PC back tomorrow. THanks.
