Flash is slow

#1
Hi, I am setting up a new server, Z840, everything works fine, but flask is extremely slow.
when I fire a flash template, it takes around 2 seconds before it shows up. movies or images are appearing instantly.
the machine is running windows 7 64 pro, SSD drives.
Installed is flash activex dev version 27. I could not install the version 11 from the caspar site, windows refused it.

thanks for any ideas
