I'm wondering whether your interleave factor on the SH has changed frpm the 10 meg modem. The interleave stats used to be displayed on the VMNG 300, but they are suppressed on the SH (I say cynically to prevent knowledgeable customers from seeing what's going on). That would affect latency.

I also think you're giving credit to VM for an obviously needed decision without chiding them for yet another debacle of releasing something that was not fit for purpose.

Regarding the MTU size, if it woeks on a router behind the SH, then it must be got working by VM on the SH itself. It's why it's there. Why those idiots didn't put modem mde onto the business SH is beyond me; false reasoning I'm sure.
