@robertsdotpm the bandwidth test works by streaming it to a temp file? Can it not just be done in momory or would that cause to much memory usage?

[robertsdotpm]

It can be done in memory and you don't even need to use pre-generated files - you can just send garbage and rely on TCP to regulate reception. The problem is: that would require writing custom code just for the bandwidth tests instead of using the existing file code which is what you suggested.

[F483]

Well if the problem is reproducible and not just a one off thing we may have to change it.

The thing that I find odd it that this is a temp file that must have been created in the same process, so what could be causing the usage by another process? Antivirus?

Disabled the windows defender (default firewall) but still the same exception.

@robertsdotpm @littleskunk is this still current?

[littleskunk]

Retest impossible at the moment. I don't get a connection to any node. I don't see any bandwidth test. I will retest as soon as possible.

[littleskunk]

I did a new test. I installed storjnode and pyp2p develop branch. This time i used the start_farmers.py.
