Q. How much CPU does yProxy use?
It will use less than 10% on a modem connection (around 2% on a fast computer). The faster the connection, the more CPU it will use. Also, it will be higher when you're downloading a yEncoded file. It will use the CPU as needed, so on a 10 Mbit connection to the news server, it could peak your CPU. But it shares nicely. It runs at the same priority as your other applications.
yProxy Pro allows you to set the thread priority!
