Network performance is critical, not just the 10 vs 100 cards, but also the hubs. It was taking over 7 minutes to recalculate a financial statement that took seconds in Plus. With the excellent support from Adagio, we ended up tracing the bottleneck to our 100mb hubs .. plugging the same workstations into a switch reduced the recalc time to 35 seconds. Not stellar, but certainly workable. Keep the switch vs hub issue in mind. Cheers!
