I did some more experiments about the performance thing.
apm -H forces the cpu to stay at 1101MHz permanently,the value it automatically set when doing something like the openssl speed benchmark.
I misinterpreted that value,however.
As
https://forums.freebsd.org/threads/f...boboost.65842/ shows,the +1MHz is a sign that turbo boost *is* supported and used,so everything is okay here.
Maybe I should just accept things as they stand currently,at least the huge boot delay could be reduced and it's fast enough for surfing.
