Logon via web problem in 5.6 & others performance questi

1. It takes so long long time to process when i submit the username & password into the web interface and sometimes i can not loged in. How do i check the root of problem?
2. How many concurrent users that can connect in the same time by using the same account?
3. Mysqld daemon always eat 99% of my first CPU. I'm very lucky that my server has 2 CPUs. So what can i do to improve the mysql performance?
4. I'm using Op5.6 by using Xeon 2 CPU (2.20GHz) + 4 GB Mem. With these hardware detail, how many clients that i can add into OpManager that running on these Xeon server.
5. We're going to buy Op5.6 but only 1 problem, i dont know what is the hardware spec that i should buy. The approximate amount of clients are 50 routers, 50 linux servers, 50 servers and the amount of server and router is increasing. Give me some guideline.
