I have built Qt 4.8.4 with OpenSSL support with MinGW (gcc 4.7.3) on Windows 7. My network application now starts very slow. Without SSL support it starts in 200 ms., but with OpenSSL support - 800-900 ms. It looks like SSL initialization takes 600-700 ms. My PC is based on Phenom II X6. Is there a way to speed up the application startup?
