 I plan to run another full test with
 ciphers="SSL_RSA_WITH_RC4_128_SHA" as development wants to keep using
 that suite, and then you and Naresh should get together and discuss
 what/when can be done.

+I didn't check jget source but it probably use the "default" JVM
+provider for crypto and SSL, which I strongly suspect is only a
+wrapper to native libraries. That would explain the very small (3s)
+difference (start VM, JIT code, ...).
+
+However I'm really surprised at the "small" difference when running
+mget on Mono and MS runtimes. MS runtime use the SSL/TLS support from
+the OS which is entirely native - there's no reason it shouldn't be
+near jget performance.
+
+Last point, Mono doesn't support EDH-RSA-DES-CBC3-SHA or any cipher
+requiring DH in SSL/TLS. The closed supported cipher would be
+TLS_RSA_WITH_3DES_EDE_CBC_SHA
+
+The currently supported ciphers are:
+TLS_RSA_WITH_AES_256_CBC_SHA
+TLS_RSA_WITH_AES_128_CBC_SHA
+TLS_RSA_WITH_3DES_EDE_CBC_SHA
+TLS_RSA_WITH_RC4_128_SHA
+TLS_RSA_WITH_RC4_128_MD5
+TLS_RSA_WITH_DES_CBC_SHA
+TLS_RSA_EXPORT_WITH_RC4_40_MD5
+TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5
+TLS_RSA_EXPORT_WITH_DES40_CBC_SHA
+TLS_RSA_EXPORT_WITH_RC4_56_MD5
+TLS_RSA_EXPORT_WITH_RC2_CBC_56_MD5
+TLS_RSA_EXPORT_WITH_DES_CBC_56_SHA
