[edk2-devel] How to optimize boot time?

Hi,

So I've a SBL+EDK2 customized firmware. This firmware enters the BIOS menu in approximately 17 seconds. I haven't seen this as a problem for a long time, but I've seen some CFL motherboards boot up the OS in 17 seconds. The motherboard I use is CFL-H. Is there a solution that will allow me to shorten this period even more?

Thanks,
Hamit Can KARACA

There is a performance logging infrastructure in the codebase. There are PERF_START/PERF_END macros that record timestamps. 

See: https://github.com/tianocore/tianocore.github.io/wiki/Edk2-Performance-Infrastructure
