Hi friends,
I have this small network comprising of around 40 users complaining about the poor speed. And they have 2900 WAN router having 10M service. The interesting thing is that they are using proxy server for all the communication.
I am very new to the server side of thing-and wanted to confirm if the proxy server is packed full to its capacity for serving to clients' requests making it slow or its something to do on the network like WAN link being overloaded or showing errors.
I did "sh interface g0/1" (WAN interface) and to me it looks there is not much load as the tx and rxload values are fairly ok. (as shown below). Moreover the output drops is 7341. I am still guessing if thats not too bad??
The other thing I did was to test the "sh ip nat transalations" which is all coming from the PRoxy server and was wondering if that is the place of bottleneck. Currently there were showing around 570 entries. Below are the output from there as well. Also, I was keen to know what is the "----" indicates in some of th output?
