Here is what I have: $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel type : primary processor cpu family : 6 model : 8 model name : unknown stepping : 6 brand id : 2 cpu count : 0 apic id : 0 cpu MHz : 897 fpu : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse > >>>I would like to have back the 1.3.x promptness ;-) > >>What time do you time for the PageDown scrolling test? > > > >I have a big .lyx file full of figures and equations which I use for > >testing.

Yes for the native win32 version. The cygwin version (I mean the version not using X11) essentially uses the same sources as the win32 version, so it has the same performance. > >LyX-1.4.2/Qt3 X11: 13s scrolls like a train till the end > >LyX-1.3.7/Qt3 native: 9s scrolls like a rocket till the end > > Thanks for the numbers, it is quite interesting. Interestingly enough, the X11 version on Windows performs much like the linux version. Here is the result I obtain with Debian/testing on the same computer: LyX-1.4.2/Qt3 linux: 10s scrolls like a rocket till the end -- Enrico
