You are receiving performance complains about a client/server-based application. Given the
following information:
Network Output Queue Length: 10
% Processor Time: 50%
% Disk time: 30%
Pages/Sec: 3
Which server subsystem is the bottleneck?
A.
processor
B.
network connection
C.
memory
D.
disk
Explanation:
Industry Standard Architecture – Student Guide 2 – Page 246:
Network interface counters
Output Queue Length – Reports the length of the output packet queue (in packets). If the length is
2 or longer, delays are being experienced and the bottleneck should be found and eliminated, if
possible. Because the requests are queued by the Network Driver Interface Specification (NDIS)
in this implementation, this counter should always be zero.
