Hi,

comparing wget and curl downloading a simple wegpage (e.g. www.google.de)
shows up that curl has 5-6 times higher impact on CPU. This was on Debian
unstable using
        valgrind --tool=callgrind curl -s www.google.de >index.html
resp.
        valgrind --tool=callgrind wget -s www.google.de

Both tools where compiled using OpenSSL.

It looks like that curl_global_init() initalizes OpenSSL though SSL is not
needed. Kcachegrind show that SSL_load_error_strings() is alone responsible
for nearly 50% impact.

Isn't it possible to only initialize SSL stuff when needed ?

Regards, Tim
