If there is a performance issue with CANoe/CANalyzer, the following symptoms can occur:
If one or more of the above-mentioned symptoms occur, please follow this instruction:
1. Optimize performance
CANoe ≥ 9.0: File | Help | Optimization. See messages in write window.
In older CANoe/CANalyzer versions see Configuration | Options | Measurement | Performance | Optimize Performance
2. Reduce Data History in File| Options | Measurement | Data history and set
3. Deactivate unused windows in View | Measurement Setup.
4. Adjust filters
If a bus system is simulated, but the data is not needed for the analysis, a filter can be used. All Measurement Setup features are not available any more. See: Configuration | Options | Measurement | Performance | Throughput. Note that you cannot use filtered data for later analysis.
5. Adapt queue size
When working with many different channels, the queue size between RT and display part is often too small. Therefore, the EventQueueSize and EventSorterLimit in CAN.ini have to be enlarged.
The CAN.ini can be found for example under C:\ProgramData\Vector\CANoe\12.0 (x64) with C as the installation drive and 12.0 as the version and (x64) indicating a 64 -bit installation. In CANoe from version 12.0 the CAN.ini is also accessible from the CANoe Help through the Windows Start menu entry Tools as shown below.
