I know my new ISP is enforcing a lot of different limitations. They refuse to say what are the limits.
To determine bandwidth I can use sites like http://www.voiptest.org/ (BTW it shows me ~15% of what I am promised to have (sic!))
I noticed that there is probably also a limit on number of opened connections. To determine it, I picked a random torrent with more than 10 000 seeders. I am able to connect up to 50. Torrent trick is easy, but it is not a perfect solution, because torrent connections are probably classified to some P2P pool with different limits.
The question is: what are another ways to determine maximum number of opened connections silently enforced by my ISP?
I Ask for ideas. I am a programmer and I use Linux. I can write some shell script, python or c code, or whatever. It's not a problem, but who to connect to not look like some DOS attacker. Do you know some host pools I can open a lot (>100?) of connections to? Any other ideas?
