Do you plan adding LZ4(much faster than gzip) support to stunnel?

stunnel has nothing to do with TLS compression. You would have to ask OpenSSL developers to add it in OpenSSL, stunnel will be able to use it then automatically. After that you would need to convince authors of all other TLS libraries to implement it and system administrators to upgrade their systems, to have anything be able to talk LZ4;) And I don't believe LZ4 was even standardized for TLS anyway.
