Is there any way of boosting the download speed?

Max

When you are downloading from a slow host which has chats activated, tell him to get a faster connection.

How to tweak WINMX settings.

For High Speed connections

Click on bandwidth button.

Set download bandwidth to 10000000 bytes per second

Set upload bandwidth to 50000000 bytes per second

Ensure ticks are in the boxes.

Then set your throttle cycle to 50m/s, this should be good if you have a good
PC with big memory, if not or you have problems reset it back to 250m/s
Throttle controls how much of the computers resources it will use. If you want to do something
else while using WinMx, then set your throttle higher and if you are going to leave
it over night then set it lower.

Use the settings and watch your speed increase dramaticaly especially if
the other user has set them the same.

I have gone from an average of 4.5k/s to 30k/s using these settings when
other users have them also.

The effect of those setting will be probably more or less a psychological one. - Honestly, that's bullshit, - and you are posting in the wrong forum anyway.
