CA Performance Reports

This page is intended to report CA performance reports from various OS and CPU architectures. The reports are generated with 'catime' which delivers with EPICS versions 3.14 and above. It would be particularly interesting if sites report different or largely varying performance on a give OS, BSP/CPU combination. In this way, we can build a known expectation.

Note: Tests were executed with the exampleApp and 'catime <user>:aiExample' which defaults to 10000 channels.
