How to use layered optimization in Adobe Acrobat?
Though canvas-layered optimization requires several different techniques, it offers a significant boost when applied properly.

How does LabVIEW update the front panel control?
Then LabVIEW updates the operation buffer that stores data at the control and redraws the control if the front panel is open. LabVIEW then sends the data back to the execution thread in a protected area of memory called the transfer buffer. LabVIEW then switches back to the execution thread.
When does LabVIEW switch to the user interface thread?
When you write to a local or global variable, LabVIEW does not switch to the user interface thread immediately. LabVIEW instead writes the value to the transfer buffer. The user interface updates at the next scheduled update time. It is possible to update a variable multiple times before a single thread switch or user interface update occurs.

Is there way to optimize single canvas render loop?
