Hi   François,

I compared both the version with Qt and the version without Qt  with TeXmacs-1.0.7 (1.0.7 version does not have a Qt port ).

I have double verified (on both my laptop and desktop computers ) that the performance of Texmacs-1.0.7 is much better than that of  TeXmacs-1.0.7.21 and 1.99 when editing long documents. The difference is most obvious when I try to delete a new-line-break: TeXmacs-1.0.7.21 and 1.99  (for both with qt and without qt) give slow response after I press the "delete" key.

Besides, the 1.0.7 version of TeXmacs seems to be much older than 3 years. So, François, the reason that you can not reproduce what I reported may be that you are using a version newer than 1.0.7 and the bugs has appeared in the version you used. In the bug report ( https://savannah.gnu.org/bugs/?42455)  you said that the revision 8087 had introduced a big overhead when processing big documents.
How about the follow-up of the bug report?

Youjun

No, I was wrong. Actually, for the X-windows version, I don't see
performance differences between current TeXmacs and a 3 years old
version on removing line break from a long document.

Which version of TeXmacs did you used?
