FC4 and xen0 performance
by Jeffrey Buell
I installed FC4 test1 and xen0 straight from Fedora and ran some simple
kernel microbenchmarks (loops over getpid, fork/wait, signal, etc.) and the
results are pretty ugly compared to a 2.6.1 install. FC4 ranges from 1.5X to
20X slower, while xen0 is about 2X to 6X slower. Is this expected? I'm
looking for configuration differences now, but I'm wondering if anybody can
comment on how FC4 and xen0 were built. debug? asserts? One difference
between FC4 and xen0 is that FC4 was configured with HIGHMEM and xen0 wasn't.
Thanks,
Jeff

I am not aware of a reason to want that aside from the special exception
of USB (which should be built into kernels, really). Do you have an
example in mind?

That's too bad, and you forgot to mention what you used it for.

Yes. Also, xen0 is configured with SMP and FC4 wasn't. My 2.6.1 has neither
SMP or HIGHMEM, but these things shouldn't have that much effect, or could
they?

Re: gnome-vfs not in Rawhide?

gtk+ will need to stay around for a while yet, for compatibility with
people's existing apps. It's not as if xmms is going away, just that it's
moving to extras once a maintainer steps up.

gnome-python(?) error
by Zoltan Kota
Hi,
I've just installed FC4 test1 and updated it from devel.
Try this:
$ python
Python 2.4 (#1, Mar 14 2005, 19:45:57)
[GCC 4.0.0 20050310 (Red Hat 4.0.0-0.33)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gnome
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File
"/usr/src/build/539346-i386/install/usr/lib/python2.4/site-packages/gtk-2.0/gnome/__init__.py",
line 13, in ?
ImportError: /usr/lib/libgconf-2.so.4: undefined symbol:
gconf_value_steal_schema
>>>
Is it a bug or I'm missing some packages? libgconf-2.so.4 is there...

So, why do init.d scripts not work for ivtv?
