Values are multiplied by 100x
Hi,
I type a value, for example, "10,00". I see in the screen "10,00" but
when print that value is multiplied by 100x resulting: "1000,00".
What can I do?
wine 0.9.55-1 Debian/Sid
Thanks.

xftrm is more than 100x slower for AsIs than for character vectors
Dear Ivan,
thanks for the confirmation and the proposed patch.
I just wanted to add some notes regarding the relevance of this: base::merge using by.x=0 or by.y=0 (i.e. matching on row.names) will automatically add a column Row.names which is I(row.names(x)) to the corresponding input table (using I() since revision 39026 to avoid conversion of character to factor). When this column is used

I() in merge (was: Re: xftrm is more than 100x slower for AsIs than for character vectors)
Dear all,
actually, it is not clear to me why there is still a protection of the
added Row.names column in merge using I(). This seems to stem from a
time when R would automatically convert character vectors to factor in
data.frame on insert. However, I can't reproduce this behaviour even in
data.frames generated with stringsAsFactors = T in current versions of
R. Maybe the I() inserted in r

xftrm is more than 100x slower for AsIs than for character vectors
Good evening,
I recently have observed slow merges when combining multiple data frames
derived from DataFrame and base::data.frame. I observed that the index
column of intermediate tables was of class <AsIs> (automatically
converted from character). The problem occurred mainly when using the
sorted = T option in base::merge.
This can be traced to xtfrm.AsIs being more than 100 times slower

...ithub.com/google/neper) as test process.
Napi increases single stream throughput, but increases cycle cost.
The optimizations bring this down. The previous patchset saw a
regression with UDP_STREAM, which does not benefit from cleaning tx
interrupts in rx napi. This regression is now gone for 10x, 100x.
Remaining difference is higher 1x TCP_STREAM, lower 1x UDP_STREAM.
The latest results are with process, rx napi and tx napi affine to
the same core. All numbers are lower than the previous patchset.

slow Perl on CentOS 5
If your Perl apps are unusually slow on CentOS 5, have a look at this blog:
http://blog.vipul.net/2008/08/24/redhat-perl-what-a-tragedy/
In a nutshell: some Perl apps are 100x slower on RedHat / CentOS 5
compared to other distributions.

disable sip registration
Is there a way to disable all SIP registration and block any requests? The
reason I'm asking is this particular Asterisk server will just be
originating calls. I've noticed sip attacks where the attacker attempts to
register a user 100x per second causing CPU to rise significantly.

Transient xen performance issue
I''m installing Xen with the OpenSUSE 10.2 distro and the
bigsmp-2.6.18.8-0.13.i586 kernel. However, I occasionally get insane
amounts of slowdown (almost 100x) in dom0. On bootup, performance is
normal. After an undeterministic period of time, I get this crazy
amount of slowdown. I''m not sure why this is the case and I have spent
a long time trying to figure it out. There are no background processes
running and nothing CPU intensive show...

One could imagine someone wanting to use it in a timing loop or
something, and a 100x or 1000x slowdown might ruin their day.
But it's not really all that important. I don't really see a good
reason to not have a separate sync_core operation, but we can always add
it later if needed.
The bigger immediate issue is that we seem to be having an emerging

Mathematica now working with Nvidia GPUs --> any plan for R?
Dear All,
I just read an announcement saying that Mathematica is launching a
version working with Nvidia GPUs. It is claimed that it'd make it
~10-100x faster!
http://www.physorg.com/news146247669.html
I was wondering if you are aware of any development going into this
direction with R?
Thanks for sharing your thoughts,
Best wishes,
Emmanuel
