looking more at it, some few hints.

Because the tls does quite a lot of memory operations inside the ssl
library, try with mem_join=0.

Also, based on the work done by Camille Oudot, you can try with tlsf
memory manager, which ensures predictability of duration for memory
operations in all cases. f malloc can be faster for common case, but in
some corner cases (e.g., lots of tls connections dropped at the same
time) can be slower than tlsf.

Cheers,
Daniel
