Measuring Bandwidth
From the perspective of the client,
Perceived Bandwidth = Bytes Transferred / Response Time
Is not a linear function of file size because of constant overhead
Perceived bandwidth is accurate measurement as long as data transfer dominates perceived response time
Aggressive clients still serviced with delays proportional to their over-activity
Use exponential averaging for bandwidth measurement
As file size decreases, measured perceived bandwidth decreases
A web server can have low bandwidth utilization and still be saturated/overloaded with small files!
