4.3 System performance optimization
4.3.1 Performance
iSTUDIO is, just as any other product, susceptible to performance limitations imposed by the different technologies
used. Practical experience has shown that iS
TUDIO will perform well under almost all circumstances. Factors that
have been recognized to influence system load to a high extend are the amount of API calls and the fonts that
are used.
API calls
If API calls are used, we advise to not exceed their number to more than 20 calls per second and to carefully
select the used API calls.
In case of doubt contact the Barco support for further information on which approach to follow for
achieving the best performance possible, please refer to section
10.1 Hotline.
True Type fonts
The extensive use of TrueType fonts is at the expense of the performance of the system, as True Type fonts re-
quire more processing power than other fonts. We recommend to take this into consideration when selecting
fonts.
Network load
When multiple H
YDRA modules work together in a wall configuration, make sure that the network segment to
which the modules are connected is not loaded too much.
4.3.2 Japanese fonts
To show Japanese fonts in the iSTUDIO GUI Windows as well as the Internet Explorer must be set to support Japa-
nese characters.
To display Japanese characters by the H
YDRA, in the dialogs of the user interface, where text is edited the font
Mincho or Gothic must be selected!
