Note that OpenBSD also disabled the openssl freelist "optimization".

CFLAGS+= -DOPENSSL_NO_BUF_FREELISTS -DOPENSSL_NO_HEARTBEAT

I used:
CC= clang
CFLAG+= -O3 -fsanitize=address -fsanitize=undefined -DOPENSSL_NO_BUF_FREELISTS -g

I also created a more readable version at https://github.com/rurban/openssl

My perl5 TODO list

Below is a formal list of possible optimizations, which most would agree on. We had these discussion in 2001 with damian were perl6 and perl5i took off. I'd like to work on these for perl5 core and need decisions. Most p5p hackers seem to be informed about the general possibilities and directions, but not all. We'd need this to improve general perl5 performance, and also help static compilation.[1]

Perl 5 is still in business but lost lot of its market share since the announcement of Perl 6. I'll outline the technological problems with perl5 which led to perl6, the management problems, and my various attempts to get perl5 into proper shape. parrot, the perl compiler, p2 and cperl. There are interesting observations in toxic cultures and technological problems.

Perl 5 is still in business but lost lot of its market share since the announcement of Perl 6 in 2002.

I’ll outline the technological problems with perl5 which led to perl6, the management problems in the p5p perl community which led to serious brain drain, the various attempts to get parrot and perl6 into shape for the last 14 years and more.
