The application was tested in order to find out how
processing power affects the video streaming and playback
performance. This test was conducted with two computer
configurations, a low-end and a high-end one. The low-end
configuration represented a computer that a common user
would have in the near future. Its configuration consisted of
Intel Core2 Duo P7450 2.13 GHz processor, 4 gigabytes of
RAM and NVIDIA GeForce 9600M GS graphics card. On
the contrary, the high-end configuration represented a highperformance
computer nowadays rarely available to common
users. This configuration contained Intel Core i7-2600K 3.40
GHz processor, 8 gigabytes of RAM and NVIDIA GeForce
GTX 570 graphics card. Both configurations had 64-bit
Windows 7 and a version 14 of Google Chrome web browser
installed, which was used in the tests. The resolution of the
used webcam feed was 640 x 480 pixels.
The test set out to establish three performance ranges,
namely minimum, maximum and average. Minimum and
maximum represent the lowest and the highest performance,
whilst average indicates the performance in the long term.
The values used to indicate performance were measured
within a ten second time span and the unit of measurement
was frames per second (FPS). FPS describes the frame rate
of the display and it can in turn be used to define the
application’s usability. Based on our rough estimate with 60
frames per second the usability would be excellent, whilst 20
FPS would still enable very fluent usability. 10 FPS is the
limit at which the performance is still acceptable, but with 5
frames per second the frames are updated so slowly that the
interactivity with the user and the application suffers too
much and the application becomes unusable.
From the results (Fig. 8) it can be seen that the
performance is good with both computer configurations. The
low-end configuration has a fluent frame rate with an
average of 18.2 frames per second, while the high-end
configuration’s performance is very fluent reaching all the
way to 35.7 frames per second. Thus, the high-end
configuration is approximately two times faster than the lowend
one.
