- Some modules had bugs in them. They were quite noticable, as I remember. I
- just don't run those modules.
-
- This machine is running 2.1, and has been running backspace for, oh, 95% of
- the elapsed time since BackSpace was released. The average uptime for my
- NeXT is about 30 days. The usual reason for a reboot is that I have to
- connect or unconnect some SCSI device, or install new software. The last
- time it crashed or froze up was, uh, gee I don't remember.
-
- There certainly were a few modules with bugs in them, but the ones I use
- don't seem to give me any problems.
-
- As for wasted cycles, just change the mach priority (it's a preference
- setting in BackSpace). This will reduce, though not eliminate, the amount
- of cycles it steals from other stuff. You can also switch which module you
- use. I tend to use the "Clock" module (on 2.1), which doesn't seem to use
- up much CPU time (I run KPerfMon so I can see how busy the CPU is at all
- times). Other modules were real pigs. Again, just avoid those modules.
