Thanks for all the info on this guys, I have no actual requirement to 
have ECDHE implemented on the servers I maintain. I was just trying to 
improve security by enabling the Forward Secrecy options where possible. 
As some of the browsers support ECDHE and not DHE, IE8-10 for example. I 
will do some more research on the issue mentioned by a previous poster 
between now and when version 4 comes out, then decide if I do want to 
enable it or not at that time.
After some playing around on the test system, testing results using the 
ssllabs test tools with various options and dhparam key sizes, along 
with the input from this thread. I have enabled the DHE ciphers on the 
production reverse proxy server that I maintain at work last night.
