I've been noticing that mouse movement response is extremely sluggish when the system is busy. This didn't seem to be the case before I got the Mac+ upgrade. I used to be able to drag disk icons around before the screen caught up to me. (Maybe I'm remembering wrong.) Now if I try it, the mouse is in a super low gear. Another behavior change that I have noticed is really poor control response in terminal emulators. If the host is sending characters, typing on the Mac keyboard doesn't send the outgoing characters right away, and menu response is painfully slow. I must hold the mouse button down for a minute or so to get the menus to appear. Very annoying! This may be a Red Ryder 8.0 problem, but I think I have seen it on MacTerminal. Is something very different about the handling of the ports by the new ROMS? More sluggishness problems: Now that I have a Mac+ (upgraded from a 128!) I have been trying more ambitious stuff. If I try to read in a large text file (200K) I get interesting problems. With MacWrite the system takes 10 minutes or so to read the file in, and then the menu response is so slow as to be completely unusable. Loading the same file into a smaller, more efficient program (MicroEmacs) takes only 2 minutes or so, and the system and program run at normal speed, but some operations like large inserts take minutes. Something doesn't seem right. I *think* that the Mac is very busy shoving data around. Could this be a problem with the Mac's memory (heap) management? I will grant that trying to deal with text files with MacWrite is likely to be inefficient, but just loading a large file into a raw text editor seems to be taking unreasonably long. Does anyone else have similar experiences? I'm wondering if this has implications on the performance of megabyte-sized programs for the Mac+.
