A campus network:
I have a pix515R and a 3640 connect to internet . The Link to Internet is 100M.when I do not use 515 , only use 3640 do NAT , the browse internet speed (download big file speed)is high ,but 3640 cpu usage is high as 80%,the concurent connection users number is small .
When I use 515R to do NAT , the web browse speed is low (as about 50kbps) , but the concurrent user connection is high , what is the matter ?How can I do?
thank you .my email:
