When connected to a service, the "feel" of scrolling in the terminal window (i.e., is it "smooth" or "jerky") is determined by the relationship between the speed of incoming data versus the speed of your computer. In general terms, a slow computer displaying fast incoming data is going to look more jerky than a fast computer displaying slow incoming data. If you prefer a smoother scrolling appearance, try the following:
(1) Keep connect speeds to realistic values. Many high-speed modem users choose a connect speed of 57600 bps because it is the highest setting available. However, unless you are using a v.34/v.fc modem and making a 28800 connection, use a connect speed of 19200 bps instead. Using this lower speed gives a better "feel" to the terminal window without any significant performance reduction.
(2) Keep the size of the terminal window at 80x24 when connected to a service. If you click in the "zoom" box while connected, this is the default size. When you increase the size of the terminal window, you increase the amount of scrolling which must be performed. The smaller the terminal window, the smoother the display.
(3) On non-monochrome computers, try reducing the color/grayscale depth. In particular, using the "millions" setting has a pronounced effect on scrolling.
(4) Certain memory management extensions such as RAM Doubler and OptiMem can cause a slight reduction in scrolling smoothness. Try disabling these kinds of extensions and see if it improves scrolling performance.
