Confirming on big compiles. vte takes time to render all the text he has in the queue. Afair if xterm has a long display queue it just "skip" to the current output. That makes sense? This bug is valid for core 2 as well... and very annoyoing too! I've seen it discussed on bugzilla.gnome.org but no real solution seems to have come out of any of it! to me this bug is important to get fixed... I frequently do some programming in vi under a gnome-terminal (or at least i would, had it performed properly) but scrolling up/down is just to painfully slow, when browsing the code for instance. please update severity as this effectively renders gnome-terminal useless. Also, please bump version to devel, as the problem is stille not fixed. It doesn't make gnome-terminal useless, thousands of people use it daily. Having a bug open for "make things faster" is not really useful since it isn't a specific well-defined task, and bugzilla is a task tracker; really the bug we need open is "the following function shows up in a profile and can be optimized in the following way" Lots of vte optimization has been done, what fixes are still possible is an open question. We have accelerated the RENDER extension in X.org server, which should make a big difference. gnome-terminal isn't useless, but it is really slow. xterm real 0m19.997s gnome-terminal real 3m54.364s *** Bug 135672 has been marked as a duplicate of this bug. *** *** Bug 75478 has been marked as a duplicate of this bug. *** Havoc, this bug has existed in gnome-terminal ever since RH8. The gnome-terminal in RH 7.2 did not have this problem. xterm has never had this problem. Accelerating the RENDER extension in the X.org server is NOT an acceptable fix. Expecting newer, faster hardware to cover up sloppy programming and/or design is the Microsoft way, and that way has no business in our world nor in the attitude of one of the leaders in our world. Hi Rick, The "vte is slow" problem is a problem that is being addressed. There are a number of performance patches out there that are being looked at and added (see bug 132770 for instance). bug 132770 says the speedup patch is in rawhide.. A cached "find /" on xterm is *ludicrously* faster. Also, xterm doesn't have the weird "page up" ghosting bug when viewing a text file with less. *** This bug has been marked as a duplicate of 132770 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
