How to Limit Download Speeds from my Website on my IIS Windows Server?

Question

When people download files from my website, I don't want them to be able to download faster than 300KB/sec per file.

Is there anyway to do this? I'm running IIS 6.0 on Windows Server 2003.

Solution 1

You can't limit download speed but you can limit the overall traffic to a particular website:

1. Open IIS MMC
2. Select Website
3. Select Performance tab
4. Enable 'Bandwidth throttling'

Solution 2

Write a script that transfer the data in chunks. After 300KB you wait until 1 seconds is consumed.

Solution 3

I just found this but I haven't had time to try it out myself IIS Bit Rate Throttlling

That doesn't really throttle the bandwidth. The 300KB chunk will still download at the fastest rate possible. If You multiply that by X users, even with a 1s delay between chunks it isn't going to have the desired effect.

How I understand the question this should limit per user. If I send only 300KB per seconds then in middle there will be only 300KB transfer rate for this user.

No what you have is a burst of data at the max available bandwith then a delay then another burst of data at max speed again. This isn't really bandwidth throttling.

You will have to make the pause very much smaller, I think, so it goes "fine", like tracing a circle with PI. Beginning it's very edged, and the edges get finer and finer until it looks like a circle.
