What can i do to be and ultrapeer?
 

If i have a powerfull computer (CPU and memory, internet connection etc.) and i want my FrostWire client to be an UP? is there someplace in the preferences i can define that?

What is the way to run my FrostWire as an UP?

The network will decide at any given moment whether it needs more UP's. It's not a user controlled issue. But to promote your chances, you should have a reasonably fast connection, free bandwidth for both uploads & downlds. You'll also need to ensure that Disable UP capabilities is not checked under Speed options. Oh ... & you need to make sure you're not firewalled. Incoming must be true. See this test: Bug Report instructions & sample image Is the result True/False?

Do i also need to stay connected for a long
 

period or i can be an UP when i first run my client? i thought that the difference will be in the tags i send in the handshake but i see that even if i don't check disable UP capabilities and i allow incoming and i'm not behind a firewall (and on a strong computer) - still i'm just a simple leaf.
Isn't there another way i can tell the GNet that i'm willing to be an UP if they need me to?

I've never been a UP, my bandwidth is not large enough. It sounds to me as though there are enough UP's already in your area to cope with demand. However, should there come a time more UP's are required, then you'll become one. I'm not sure how long after opening LW you can become a UP. Someone else may be able to answer that. From what I've heard, the time it takes can vary.

Since 4.9.30, FW cannot become UP at startup. To become UP you need a high average uptime and a network in need for UPs ;) For the bandwidth needs, it is ridiculous, like 8KB up and down... (an UP only consumes avergae 4 KB/s up and down)
