Hi,
currently I am using urxvt as my standard terminal
application, which is FAST and reliable.
But it only emulates 24bit colors if instructed so.
It maps 24bit rgb to 256 color using a fast but not
total correct formula to to do (which is no critism -
its just the way ot is implemented).
I googled qyite a bit to find 24color terminal
emulators and the one, which came closer to
what I want is sakure.
But comparing the speed of sakura with urxvt
(catting a long log file twice while measureing the time
of the second cat) it shows that sakura needs
six times more time than urxvt.
Combining this with the compile sessions, which
are one of the core features of Gentoo ;)))...
What I want is the "fastest" possible (...)
terminal emulator supporting true color (24bit).
I dont need fancy configuring options (two exception:
TABS! and lightweighted) and I dont want KDE stuff (or
any other bloated thing with thousands of dependencies...)
I am simply using openbox.
What are your experiences?
Any hint is heartly welcome! Thanks !
Cheers
Meino
PS: The terminal emulator dont need to be part
of Gentoo necessarily...if it is compilable
by a human being withoyt super powers... ;)
I am using rxvt-unicode also as my main terminal emulator. Its true colour
emulation bothers me also but just only a little bit.
As a second one, xfce4-terminal runs here from time to time (seldom). A
quick time/cat test with a gcc-5.4.0 log file (approximately 25 MiB) shows
surprisingly that xfce4-terminal runs six time faster than rxvt-unicode.
Maybe one reason is that urxvt looks for URLs and email addresses to
colourising them.
Maybe you can get a suggestion from [1].

Hi Floyd,
thanks for the informations! :)
A few minutes ago I emerged xfce4-terminal and tried the
cat-time-test of yesterday: 29 secondes with xfce-terminal
and 5 seconds with urxvt. Hmmmm...
You have got the reversed results compared with mine...
What the heck slows down the output of the terminals on my
Gentoo and only let urxvt shine?
Possibly your use flags and/or openbox (if not using a GL compositor). Try
enabling all GL related flags for the terminal emulator and it's
dependencies and use a GL compositor like kwin or compiz. Modern graphics
cards are designed with modern software in mind. Many don't even have a 2D
engine anymore.

PS: I found XVilka before. That's why I asked for some experiences
of other users.... :)

Hi Fernando,
thanks for the informations! :)
I am not using compiz or such....
Openbox is installed as follows:
[I] x11-wm/openbox
Available versions: (3) 3.5.2-r1 (~)3.6 3.6.1 **9999
{branding debug imlib nls session startup-notification static-libs svg xdg
PYTHON_TARGETS="python2_7"}
Installed versions: 3.6.1(3)(11:01:40 AM 02/18/2017)(nls session -branding -debug
-imlib -startup-notification -static-libs -svg -xdg PYTHON_TARGETS="python2_7")
Homepage: http://openbox.org/
Description: A standards compliant, fast, light-weight, extensible
window manager
My USE_FLAGS (make.conf) are:
USE="nvidia X lua sdl mp3 flac jack alsa gtk cairo sndfile qt3support kpathsea gif
tga jpeg png jpeg2k mad dvb dvdr encode lzo bzip2 ogg sox v4l v4l2 vorbis x264 x265
zsh-completion -hal -lirc"
Wpuld you suggest to change a flag?
I would start by enabling opengl globally. Then look at the dependency
graph for the packages that you want to accelerate (especially the
toolkits and the whole x11 stack) and if any of them have egl or gles
and not opengl then enable it. You can't enable them all on make.conf
because sometimes they conflict.
Thanks a lot for any help in advance!
Cheers
Meino
