Performance Engineering – Why so many companies don’t get it – Part 3
In the previous 2 posts we described several ways in which sub optimal performance engineering practices manifest themselves, as well as identified the lack of goal commonality between developers and performance engineers as one of the key reasons behind these sub optimal practices.

Monday, January 25, 2010
WAN symptoms in question are latency, packet loss, disconnects, bit errors, etc. usually exist on Wide Area Networks and as a result cause applications performance degradation. But our WAN’s essentially are LAN’s connected with each other and those connections impose geographical distance between those LANs, thus creating “WAN behavior”. Inside individual LANs those issues happen [...]
