| Super genies do give a performance impact
on the update speed of the super genie page. As super genies are
associated with the physical IO Devices tags at runtime, the Citect
compiler cannot optimise the reading of the tags completely. This
optimisation will be done by the I/O Server, after the I/O Server
has optimized the requests the same physical reads should be done
to the I/O Device. So there should be the same communication
performance to your I/O Devices. However there must be more
communication between the Citect Client displaying the super genie
and the I/O Server. This communication can have a slight
performance impact.
If the Citect client and I/O Server are running in the same
computer or the network between the two computers is lightly loaded
or the number of variables is less than 20 you will not notice this
impact. The amount of impact on the performance will depend on the
design of your project and the network environment. The best way it
to test your system and see how fast it runs.
Because of this slight performance impact, if you don't need to
use a super genie you should use a genie or normal graphic page.
Normal genies don't have any performance impact at runtime becase
they are resolved by the Graphic Builder and the Citect
compiler.
