As usual, i'm using a spare 386sx/16 with 6 MB RAM for this. I noticed that the installation procedure became *awfully* slow now. At the first attempt, i've even given up since i thought the installation was dead. The machine were stuck with the ``Creating root file system'' message. Eventually, after about a minute or so, it continued. This slugginess continues all the time. The strange thing is that it's for no apparent reason. It's just ``sitting there'', no disk activity, screen echo on the holographic shell yes, but no command execution. Once it's going on again, everything works as `quick' as usual, even the response to an `ls' command on the holographic shell is within less than a second then. I've first noticing this at the fixit floppy on the same machine, btw. The floppy works fine on a faster one, but on this slow box, it continuously falls back into ``deep thinking'' every now and then. Does anybody have an idea how to investigate the bottleneck? -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
