Certainly this can have an effect,which is why I timed both.
From my combined backend+frontend (1.4 seconds to change, 2 to start)
and the remote frontend (1.8 seconds to change, 2.3 to start).
Not even close to the 8-15 seconds some are seeing.

I found it quite improved after Isaacs big rewrite.

In my case the backend+frontend is a XP2500+,
My remote frontends are all diskless nfsrooted machines varying
in cpu from 733MHZ MSNTV units to 1.2G AMD based pc's

I have 3 tuners in that backend and often are all in use,
as for what sort of PCI latency settings in use at the moment
I have no idea. I certainly didn't set anything specific.

10/100 here. Varying nic's on the network.
