Qualify the hardware platform
If the hardware platform shows poor real-time performance, use of the INtime Platform evaluation tool might be considered.
The results of the INtime Platform evaluation tool requires a good understanding of the x86 processor and PC architecture. These results can highlight some potential problems with the CPU configuration. It should not be used as a go/no-go tool without validating the platform by running INtime.
Many test issues flagged red, or orange can be solved by proper configuration of the BIOS or UEFI. However, a flagged issue may not result in an actual problem. Many platforms for example, enable SMI, but never use them during runtime.
If the BIOS/UEFI does not allow configuration of flagged issues like SMI/SMM (which often is the case for PCs intended for office-use), you may need to talk to the firmware engineers of your system’s vendor - or look for a PC designated for embedded use.
