Re: slow performance thru site to site VPN (speed issue)
It could be an MTU issue. I have had a lot of problems with this over VPN. The overheads of IP-Sec mean the FW has to fragment the packets to fit them down the tunnel and this slows things up - the thing is that from my experience it's not very obvious that it's happening!
The easiest way to find out would be to adjust the MTU of the Oracle machine and see if that makes any difference. It's not an exact science it would seem so setting it to 1440 was pretty successful for me and might be good for you.
If that works there are things you can then try to get the servers to work this out on their own but again, it doesn't seem to be particularly easy and doesn't always seem to work!
