Run a sysbench

The performance difference between CSM and UEFI mode should be just about 0. UEFI code is mostly active when ArcaOS loads. Once the OS is loaded the impact of the UEFI loader is well under 1% is not lower.
GPT filter driver will have about a max 15% impact.
Measure it then you know what you are dealing with.
