Why was running CP/M so slow? I never got to run it but I don't think of CP/M as being a particularly bloated/slow OS; but you say it wasn't the fault of the Z8

Why was running CP/M so slow? I never got to run it but I don't think of CP/M as being a particularly bloated/slow OS; but you say it wasn't the fault of the Z80. Something particular to the C128?
- anyfoo 6y agoI haven’t done any independent research (other than trying it out in a C128 emulator and concluding that it indeed feels very slow 8) ), but there is a detailed answer here: https://retrocomputing.stackexchange.com/questions/2361/why-does-the-commodore-c128-perform-poorly-when-running-cp-m https://retrocomputing.stackexchange.com/questions/2361/why-... The issue does not seem entirely clear cut, but from the looks of it, while apparently the newer CP/M 3.0 used there does seem a bit slower than earlier versions, the majority of the reasons seem indeed pretty specific to the C128.
