Hardening and performance


Do you think the ClipOS hardening flags slow down the system?

Moreover do you think the ClipOS is suitable for Real-Time embedded systems?

Hi ruben,

It is hard to give a general answer to this question without a specific benchmark to run or a concrete use case to mesure. Generally speaking, a CLIP OS system is unlikely to be significantly slower that a generic recent Linux distribution. The main changes that affect performance are (non-exhaustive list):

CLIP OS is based on the Linux kernel thus we are constrained by the real time support available upstream (see Real-Time Linux Wiki & Real Time Linux). If this is enough for you, you may create a variant, apply the patch and change the kernel configuration to suit your needs.

If you need something smaller than Linux, you should have a look at the WooKey project which specifically targets embedded systems.
