Results:

|
|
|
|
for
high bandwidth and slow client, offloading decoding agent to
|
|
proxy
can speed up application performance by a factor of 20 and
|
|
|
reduce
power consumption by 95%
|
|
|
|
|
For
faster client devices, independent of bandwidth, no benefit

|
|
(actually
worse performance) when decoding sound samples in
