Greg, there's a lot more to it than this. Gigabit LAN is bottlenecked by
the speed of the PCI bus and in real terms is around twice as fast as
100baseT if you are lucky.
Peter,
4 seconds to open a patient's notes, versus 25+ seconds, sounds more
like 6 to 1 to me. The systems I've set up with onboard gigabit NICS and
switch record 55 MBPS, using Sandra as the measuring tool, against 9-10
MBPS for 100 mbit NICs and switch over the same cables.
I know that on a properly set up PCI-X bus, their rated speed is more
like 90+ MBPS, but we are talking about making life easier for GPs now,
not some other time. And yes, I expect MD3 to be much faster, as it is
client-server and will send less traffic over the LAN.
However, like TS, the penalty is the need for a more robust server, and
possible serious additional licensing costs, especially for larger
practices where the MSDE won't cut it. For smaller practices TS is not
cheaper, and if implemented in larger practices, properly, needs a very
good server and reliable, not moribund, clients with good graphics, as
Horst has suggested. Also, the advantages of TS diminish further if you
are using a client-server application in the first place.
