OpenSSH performance with VIA padlock
Hello list,
please spend a minute considering these facts and maybe there is something to
improve:
1) VIA Eden based board can write AES256 encrypted information on HDD at >
60MB/s
2) iperf shows NIC speed 69MB/s
3) openssl tests have even better results
4) openssh can transfer AES256 encrypted information at < 27MB/s (and worse
with HDD encryption)
It is better with openssh 5.x, than 4.6, but still I see no reason why results
are so bad... Please, could someone expla...

exhaustive-model-search issue results in multi-gigabyte FLAC file
Hi,
On a particular input file, FLAC (testing with current git) greatly
inflates its output if I encode at level 7, which enables
--exhaustive-model-search. The source is a 24-bit WAV file of about
60MB; flac -6 encodes this to a 43MB FLAC file, but flac -7 produces a
9.1GB (!) file.
The enormous file does seem to be perfectly valid, FWIW -- it
(eventually) decodes to a WAV that's identical to the source file.
The copyright on the offending file belongs to the band that uploaded it
to our...

slow speeds with Windows 10
I was transferring a file from a (slow) smbd server running on some NAS.
The transfer speed is only 1MB/s but the NAS uses 100% CPU. Normally the
NAS can handle 60MB/s download (from the NAS).
Could it be that the connection uses encryption or something?
What could be causing this slow speed?
I have internet download speeds over this same connection surpassing
5MB/s. I cannot imagine why something like this would be so slow.

cannot install codeweavers wine
...am trying to install the Codeweavers version of wine (pre-release 2)
and I am having problems. When I try to install (using rpm), I get the
message "installing package codeweavers-wine-20010112-1 needs 7Mb on the
/ filesystem". My / filesystem is not overly large, but I still have
approx 60Mb available on /. Is the error stating that the install
requires 7Mb on /, or it needs 7Mb more than what I have available?
Also, why is it wanting to install at the / level and not in a somewhat
less dangerous partition? The other filesystems have plenty of room
available.
Has anyone else seen this...

Recommendation about an usb wireless adapter to use it as HostAP
Hi all,
I would like to install/test CentOS 7.X as a hostap for my home. I am thinking to use an Alfa (http://www.alfa.com.tw) usb wireless adapter or TP-Link. BUt there is not much information in Alfa's or TP-Link's web sites about which of them can run as a HostAP. If I can find any adapter that supports ac with a throughput of 150 Mbps/300Mbps, it would be great.
Any recommendation?

domUs with iSCSI disks... connect in dom0 or domU?
...p that way instead, and it
works as expected though it seems to perform less well in some admittedly
simple tests using dd with ''oflag=direct'' set. The dom0 can write at about
110MB/s sustained, but if the domU makes the iSCSI connection instead it''s
doing well to manage 60MB/s.
So I''m looking to the wisdom of the list, is it crazy to set things up one
way or the other, or are they both an OK approach? It seems like having the
dom0 handle the iSCSI connection is a big win performance-wise, but perhaps
that comes at a big negative cost? Having the domU make t...

performance of pv drivers for windows
...drivers made at least about 30MB/s reading and writing
sequentially, but for reading and writing randomly, it was also only lousy
1.5MB/s.
Via network, over the GigaBit line, with the xensource drivers, the speed was
about 78 MB/s.
The Windows system was a XP SP2.
hdparm on the dom0 gives about 60MB/s.
The network test was an ftp transfer, just downloading a 500MB file, without
writing it to disk, writing to nul. The same in the dom0, writing the file
to /dev/null gave me 112MB/s.
So I am wondering, what are the expected speed gains for the gplpv drivers?
Is the performance of the drivers b...

Very slow performance on Sharded GlusterFS
...and higher
Downloading a large file from internet and directly to the gluster:
250-300mb/s
Now same test without Stripe but with sharding. This results are same when I
set shard size 4MB or 32MB. (Again 2x Replica here)
Dd performance: 70mb/s
Download directly to the gluster performance : 60mb/s
Now, If we do this test twice at the same time (two dd or two doewnload at
the same time) it goes below 25/mb each or slower.
I thought sharding is at least equal or a little slower (maybe?) but these
results are terribly slow.
I tried tuning (cache, window-size etc..). Nothing helps....

any more efficient way to transfer snapshot between two hosts than ssh tunnel?
Assuming in a secure and trusted env, we want to get the maximum transfer speed without the overhead from ssh.
Thanks.

Slow windows network with gplpv driver.

Doing most of the testing on a xen system that currently is not in production.
Running xen 4.0 with 2.6.32 kernel from lenny backports.
Have xp service pack3 freshly installed with no updates.
Installed gplpv gplpv_XP_0.11.0.213.msi
hdtack gives 60mb/sec which is good
iperf gives ~15Mbits/sec
Without gplpv is about hte same.
A linux pv domu gives 686Mbits/sec
Shows it as using Xen Net Device Driver.

mclapply memory leak?
...a memory
monitoring program such as htop, and then executing the following code
while looking at how much memory is being used by the system
library(parallel)
seconds <- 5
N <- 100000
result.list <- mclapply(1:N, function(i)Sys.sleep(1/N*seconds))
On my system, memory usage goes up about 60MB on this example. But it does
not go up at all if I change mclapply to lapply. Is this a bug?
For a more detailed discussion with a figure that shows that the memory
overhead is linear in N, please see

speed. My own system has a habit of setting usb2.0 interface to
1.1-speeds for example.
With (hopefully) bootable USB3.0 interfaces coming soon, a MEMDISK
combined with a sufficient sized disk image (say 170MB Parted Magic
cd-image file) would show loading speeds between 60MB and 500MB if a
suitable device (USB3.0 Flash Drive or USB3.0-connected SSD) is used.
Unfortunately I'd have no idea how to take compression (gzip/zip) into
account, it can alter numbers significantly.

Basic Encoder Help
Hello all,
I've been writing a basic encoder using libFLAC++. It seems to work fine, as in the resultant file is playable in any FLAC compatible player, however the compression ratio is very small - the main example being a 60MB file compressing to 54MB, i guess there's an option i've missed, but i cannot track it down. I was hoping someone could point it out for me:
FLAC::Encoder::File flac;
void setup()
{
FLAC__FileEncoderState state;
flac.set_filename(output_filename.c_str());
flac.set_channels (2);

performance problem with windows 2003 client
...w dropping to less than the
size of a frame at any time.
I assume this is windows client-side behavior, I'm not even sure if it's
samba-specific at all, but I don't have any windows file server that I
expect would be able to push 50MB/s consistently to test against. I get
close to 60MB/s using a CIFS mount locally on the samba server.
Any suggestions or recommendations would be appreciated.

is there a bandwidth limit per file?
...sfer rate of about
10MB/s (again for read and write)
with 3 files it is even around 11MB/s. Why i can't reach this transfer
rate with just one file? It is the same from both windows pc.
I benchmarked my network around 11.5MB/s are reached using netio
(Win-Win,Win-Debian).
The HDDs are reaching 60MB/s with hdparm -t /dev/sd?
I search for such an issue, but didn't find something useful. I looked
into the documentation, but didn't find some hints for that issue.
How can i find the bootleneck in the system?
Best reguards,

Is it possible to reduce the number of workers for rpcd_winreg?
...recently updates our samba addc's to 4.18.6 (from 4.7.7). We use roaming profile and a login script which queries active shares and printers on the logon servers. Since the update i see a lot of
rpcd_winreg processes if an user logs on. It are around 40 of these processes each consuming around 60MB. The servers have 1-2GB of ram assigned so they start swapping everytime an user logs on. The
processes disappear after 1-2 Minutes and the free memory goes back from 50MB to ~1.2GB (on an 2GB server).
Is there a way to limit the number of workers so i can avoid swapping?
So far i found "prefo...

HighPoint RocketRaid 454
...t about 5-20MB/s
(totally) and I know that a single drive will handle that, but I'm unsure
if the HPT 454 is really stable in FreeBSD.
We'll be running this on a 4.8 installation.
Now to my questions...
Is the HPT 454 card & driver production stable?
Do you think that it will handle 60MB/s (read)?
Has anyone had a drive failure with this card and successfully replaced it
while the system was running or am I placing my hopes too high?
