slow-connection

I'm testing a IPSec config between 2 hosts, using ipsec auth with preshared key, very simple configuration.

(I want to start with a IPSec simple preshared key config, and then step up to a Certificate or kerberos...)

The problem is:

The connection is working but when accessing network file shares the first time it's very slow.
On the same host i'm testing the shares, i have an IIS site running, and the performance seems very normal, fast.

Does anybody know why does SMB shares are soo slow?

Is there any ipsec policy options that should be tweaked?

Thanks
