No, this is not the problem. > The question remains, what changed in 1.6 in terms of new library > usage that might have caused this increase in resource requirement? This is indeed the right question. Do you use the same qt version for the two LyX builds? If you have some time to spend on this, the tool that might help you to diagnose this is oprofile. http://oprofile.sourceforge.net/news/ It takes some time to get used to, but it gives information on the whole system (including X). If you feel lazy, there is also sysprof http://www.daimi.au.dk/~sandmann/sysprof/ which is simpler and has a GUI (but John Levon will hate me for proposing that, especially since I am not really used to thoses two tools).
