Bonding performance question
I have a Dell server with four bonded, gigabit interfaces. Bonding mode is
802.3ad, xmit_hash_policy=layer3+4. When testing this setup with iperf,
I never get more than a total of about 3Gbps throughput. Is there anything
to tweak to get better throughput? Or am I running into other limits (e.g.
was reading about tcp retransmit limits for mode 0).
The iperf test was run with iperf -s on the

FW: R memory management
Hi,
I'm using R to collect data for a number of exchanges through a socket
connection and constantly running into memory problems even though task I
believe is not that memory consuming. I guess there is a miscommunication
between R and WinXP about freeing up memory.
So this is the code:
for (x in 1:length(exchanges.to.get)) {

slow creating files
We tried to migrate from old Windows fileserver (p4, single HDD) to
Samba (FedoraCore15, Samba 3.5.12-72.fc15, ext4 volume, xeon, raid5).
Our pipeline is so, that some special software generates files on that
fileserver.
The typical filesize ~50 mbytes.
On the old hardware, software (win2k3 server) the time of single file
creation was about 10 seconds. On the new configuration it takes 20-25

Samba and Window XP write performance
I did some testing using samba-3.0.0 as a server and two identical clients
one Running W2K and other running Win XP pro.
If I write a big file using the W2K client, I'm getting about 25 Mbytes/sec
but if I run the same testing using the Win XP Pro, this
client only is able to get 12.5 Mbytes/sec.
There is a problem between XP and samba?

HoltWinters() - p-values for alpha, beta and gamma
Need your expertise for the theoretical approach to
deduce the p-values for the level, trend and
seasonality parameters. I wonder if there's source

Gluster native client very slow
Hello,
I'm testing a two nodes glusterfs distributed cluster (version 3.3.1-1)
on Debian 7. The two nodes write on the same iscsi volume on a SAN.
When I try to write an 1G file with dd, I have the following results :
NFS : 107 Mbytes/s
Gluster client : 8 Mbytes/sec
My /etc/fstab on the client :

performance with libvirt and kvm
Hi,
I am seeing a performance degradation while using libvirt to start my
vm (kvm). vm is fedora 12 and host is also fedora 12, both with
2.6.32.10-90.fc12.i686. Here are the statistics from iperf :
>From VM: [ 3] 0.0-30.0 sec 199 MBytes 55.7 Mbits/sec
>From host : [ 3] 0.0-30.0 sec 331 MBytes 92.6 Mbits/sec

performance on small files transfers
Hi all,
I'm confused of small files (no bigger than 50k )
transfers speed through samba,which is very slow on
my machine. Bellow is a real case,
-- SuSE professional 9.2, kernel 2.6.11,Samba 3.0.14a,reiserfs
-- Dual AMD Opteron,4G mem,Giga byte LAN
-- 2 raid 5 make up of 16 SATA hard disks
-- set readhead to 1024
I tested raids speed using bonnie++ and get 450 Mbytes/s

Memory leak in R v1.5.1?
Hi,
I am trying to minimize a rather complex function of 5 parameters with
gafit and nlm. Besides some problems with both optimization algorithms
(with respect to consistantly generating similar results), I tried to
run this optimization about a hundred times for yet two other parameters.
Unfortunately, as the log below shows, during that batch process R
starts to eat up all my RAM,

b89 xVM Source tar bundle is corrupted on the on download site
Apparently the b89 xvm-src.tar.bz2 tar bz2 archive is corrupted / truncated
on the b89 source download page:

In the past, the xvm-src.tar.bz2 file had a size of ~ 100 mbytes;
with b89 the size of the downloadable archive is only 72 mbytes.

Some metadata missing, relaying icecast1 stream with icecast2
I'm relaying an icecast1 mp3 stream with icecast2. This works fine,
and the song title is displayed correctly no matter if I use
<relay-shoutcast-metadata>1</> or not on the relay.
But, the stream name and other metadata provided by ices0 on the
icecast1 server is not displayed in the listening client.

rsync-2.5.6 performance sucks between winXP and Solaris8
If I try to rsync OpenOffice-directory (OO as an example, 155 MBytes)
to Solaris8-machine/rsync-server it takes 4-5 minutes, about
70 MBytes gets transfered and eventually rsync.exe/winXP "dies"; actually
winXP's net doesn't responde anymore and I have to boot whole machine!
But when I try to do same between Linux and Solaris everything
works fine, transfer speed is about

Gigabit Throughput too low
Hi I was wondering if you ever got better performance out of your
Gigabit/IDE/Fc2?
I am facing a similar situation. I am running FC2 with Samba 3.x
My problem lies in not that I am limited to 10 MBytes per second
sustained. I think it's related to this pdflush and how it's buffers
are setup. (I have been doing some research and before 2.6 kernels
bdflush was the method that was used and

Decent Performance
Hi all,
I am trying to get some decent speed out of a vanilla Debian (Proxmox) box and
am running out of ideas. Basically I can exchange data at 110MB/sec (raw, nfs,
ftp) but not with Samba shares.
I tried almost every samba tuning tip I could find to no avail. The only
optimisation left to smb.conf at the moment is debug level = 0. As one can see
the robocopy throughput is merely half of what

Request for feedback
A number of years back it became necessary to limit the size of messages
that could be posted to the samba mailing list. The current limit is 64
KBytes.
While it continues be be desirable to block large spam messages, I
believe it is time to ask current subscribers for their preferences.
