'xtfrm' performance (influences 'order' performance) in R devel
Hello everybody,
it looks like the presense of some (do know know which) S4 methods for a
given S4 class degrades the performance of xtfrm (used in 'order' in new
R-devel) by a factor of millions. This is for classes that ARE derived
from numeric directly and thus should be quite trivial to convert to
numeric.
Consider the following example:
setClass("TimeDateBase",

[LLVMdev] Measurements of the new inlinehint attribute
Friday I enabled the inlinehint function attribute in the inliner. It mostly affects the performance of -Os compiled code. I have made some measurements on the SPEC test suite to show what it means.
I made three runs of then nightly tests. The baseline represents -Os with no inlinehint:
make TEST=nightly OPTFLAGS=-Os EXTRA_LOPT_OPTIONS=-inlinehint-threshold=0

investigate & troubleshoot speed bottleneck(s) - how?
hi guys/gals
I realize that this question must have been asked before, I
sroogled and found some posts on the web on how to
tweak/tune gluster, however..
What I hope is that some experts and/or devel could write a
bit more, maybe compose a doc on - How to investigate and
trouble gluster's speed-performance bottleneck.
Why I think such a thorough guide would be important? Well..
I guess

help with x config on centos 5.1
Hi all,
Typically I dont have issues with configuring X. However this time its
an issue.
I have an NVIDIA graphics card trying to do 1920x1080.
If I configure the screen by hand with the nvidia config utility it
works at 1920x1080.
However when I reboot its 800x600. When I use the nvidia config utility to
set 1920x1080 then save the xorg.conf file, and reboot (yes I copied
/tmp/xorg.conf to
