Before you get mixed up you should know that Usenet Server and Usenet Provider both mean the same.
Usenet Server Access
Besides the inlog data, hostname and ports. Usenet Servers also offer concurrent connections. These are the connections to the server of the Usenet Server from your PC. The more connections you have the faster your download speed will be. Our registered members with experience rated usenet providers for you, so you can learn from their experiences.
But if you want to achieve download speeds over 1 MB/s there is one other very important thing you should know. The Usenet Server does not replace your Internet Service Provider. If you have an ISP downstream of 20 MBIT/s your fastest download speed will be 2.5 MB/s. Why? ISPs always measure in BITS instead of BYTES. In order to calculate the BYTES per seconds, you will have to divide the BITS by 8. You can check your downstream here.
