Max download speed is 768KB/S. Is there anything I should tweak? I really would like to get the lowest latency possible for distant servers. Since im from South America and I basically play games hosted in NA or EU.
Thanks for your time!

Edit: Forgot to ask, where can I find the exact max connection per server value? Should I set it in Firefox also?
