HI,

Request approval for :
7157903 JSSE client sockets are very slow
for 6-open

webrev :
http://cr.openjdk.java.net/~mbankal/7157903/webrev.00/

Nagle Algorithm (TCP_NODELAY) which affects small packets is false by 
default.
As a result, the kernel was throttling the JSSE output waiting for the 
peer's TCP ACK
before sending the next packet. Fix is to combine the small/output 
packets if TCP_NODELAY
is not active.

JDK8 and JDK7 integrations :
