There's bound to be a lot of opinions on this, but I'd say it depends more on what hardware you're using and what you're trying to run in the foreground and how fast "high-speed" means to you. -- "What is politics, after all, but the compulsion to preside over property and make other people's decisions for them."

I use Z-Term and under System 6.0.7, My 5/105 IIsi, and my Practical Peripherals modem, I was able to achieve about 98% efficiency running MF 6.1b9. Now under System 7.0, I can only obtain about 94% efficiency. Because of this change I am led to believe that either A) Z-Term doesn't work as efficiently under System 7.0, or B) something with Dave Alverson's Z-Modem algorithm isn't getting along as well with the way the ports are handled under System 7.0. Any comments?
