Streamer Length and Power Input--What's the problem with my coil?

Hi All,

I have recently completed a small-medium size Tesla
coil that is currently arcing about 3-3.5 feet. Specs
and sparks can be seen here:

However, I believe that this is a very low effieciency
considering that the input is 2.5-3 kVA and that I
should be getting 4-5 foot sparks. This is not the
case. Can anybody take a guess as to what is causing
my dismal efficiency?

Regards,

Chris
