Overview
Last week, one of my client reported that their users were experiencing slow internet access even on non peak hours. For them, this is because there was a problem on our proxy solution provided (McAfee Web Gateway). I don't buy that. So what I did is to gather info first (like what a good IT guy would do) and then analyze each.After some hour analyzing the result, it turns out that the culprit was their internal DNS! It seems their internal DNS is very slow in resolving each request sent by our proxy solution. This make user browsing experience very sloowwww. :(
