Hi Boost experts:
     I build a https server from asio example of server2, let it support
ssl.we use the codes from:
*https://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/http/server2/main.cpp
<https://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/http/server2/main.cpp>*
*https://www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/example/ssl/server.cpp
<https://www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/example/ssl/server.cpp>*
     I complie the codes with boost_1_64 and openssl-1.1.0j, the commed
line of complie is:
*g++ -g -Wall -o https_server2  *.cpp   -I/usr/local/include/
-I/usr/local/openssl-1.1.0j/include -L/usr/local/openssl-1.1.0j/lib
-I/usr/local/boost_1_64_0/include
/usr/local/boost_1_64_0/lib/libboost_thread.a
/usr/local/boost_1_64_0/lib/libboost_system.a   -Wl,-Bstatic -lglog
-lunwind   -Wl,-Bdynamic -lpthread -lcrypto -lssl  -ldl -lrt*
    I test the https_server2 by ngrinder, the TPS is just 400, If I test is
just http request , the TPS is 36000. So  https significantly reduce
performance.
    The perf top result is:

    The top result is:

When I test it by http request, the top result is:

    I have push the codes on github.
https://github.com/lxlenovostar/Programming_language/tree/master/cpp/test/server2_https_github
    I test 2, 4, 8, 24, 32 threads,but this can't improve the TPS.I test
the nginx with 32 worker process, The TPS is  about 5000.
    So maybe lock in asio ?

btw:  cpu is 32 cores, and Intel(R) Xeon(R) CPU E5-2440 v2 @ 1.90GHz
        memory is 66GB.
        os is CentOS 6.5
        kernel is 2.6.32

Thank you.
