Windows 98 SE is visibly very slow; and when qemu is run with -no-kqemu, it is actually faster. I have this issue on two different systems: - Intel Celeron 2400 CPU, 512M RAM, RH9-derived, kernel 2.6.11 with some patches including -ck - AMD Duron 650 CPU, 256M RAM, Debian sarge, vanilla kernel 2.6.15 (run with -m 64) On the Intel system I also installed NT 4.0 (in a different image) and it is fast with kqemu. (It has mouse problems - invisible wall, erratic behaviour, all intermittent - but I know this issue is quite different and patches exist). This same issue was also reported on the user forum: http://qemu.dad-answers.com/viewtopic.php?t=1476 However, other people on IRC have reported that Win98SE is fast for them. In fact I have transferred my Win98SE image to another person, who runs qemu CVS and kqemu 1.3.0pre7 on Ubunto dapper; he reported that it runs fast. This seems to be an issue on some systems only, but I could not isolate the key setup difference. I would be most interested in helping to pinpoint the problem. I am ready to run any tests/patches, and I have an archive of various old Windows systems (backups...) that I can try on request; I can also pull CVS if necessary. -- Yours, Mikhail Ramendik
