I'm using emacs 23.0.60 on Linux with font "DejaVu Sans Mono". And I'm expiriencing slowness when redrawing buffer filled with any text (doesn't matter - with any font-lock or without). For example, if i fill all buffer with "0" then repainting of all emacs window, when scrolling (with C-v, M-v), takes about 1 sec (or a bit less, but i can really see how it redraws window line-by-line). I googled about this problem, and find nothing, except one email conversation in this mailing list: http://lists.gnu.org/archive/html/emacs-devel/2008-04/msg00045.html which seems describing very similar problem. I've tried to checkout and build last version from CVS and it seems to have same issue. I've tried on another machine to run 23.0.60 version, and there is same problem. On Windows, no such problem was seen by me. Machines configuration: 1. Compaq Evo n800c notebook" 2.2 GHz Pentium 4-m 1024 mb RAM video: ATI mobility Radeon 7500 (32 mb) videodriver: "radeon" 2. Desktop 2 GHz Athlon-XP 512 mb RAM video: GeForce MX400 (32 mb) videodriver: "nv" Additionally, i've tested on 1st and 2nd machines xterm redrawing with same font and don't see this trouble on xterm (so, painting can be fast), on 2nd machine it was noticeably slower, but not as slow as drawing in emacs. What else information can I provide or tests can i do, to collect more information to help trace this issue? I have rater big amount of free time now and will be happy to help make emacs better. (: Sorry for my english. -- E.L.K. Saturday, 07 of June, 2008, 13:34 عظ. C_U_L8r!
