Hi,
   I have been struggling to understand an issue with low SSL transfer
throughput from Jetty 9.1.2.

I am using wget to download a large 70 MB file over https from a stock
Jetty 9.1.2 web server.  I used wireshark to determine that the cipher is
set to TLS_RSA_WITH_AES_128_CBC_SHA.  The throughput of the transfer is
consistently ~400 KB / sec.

I couldn't understand the low performance so I wrote my own very simple
"bare metal" JSSE SSL client & server (Blocking I/O) to compare.  This
configuration will transfer the same file between the same endpoints at 4
MB / sec.  Wireshark confirms the cipher is the same
TLS_RSA_WITH_AES_128_CBC_SHA.

Needless to say, this doesn't make *any* sense to me. Any tips or advice
would be appreciated.
