If this is a migration I find that tar to the local machine, copy over,
restore, then rsync are likely the best options.
In my experience copying lots of small files is going to take a long time,
no matter which method you use.
>From all the combinations I have tried in the past tar first then rsync
worked best for me.

The major factor affects the performance the the number of files in "PER" directory.
If I got impression correct, there are 5M files in JUST one directory. If this is true, then it is the problem.
The best way to avoid performance penalty is to sort different files into differet named directories.
Each directory should contain about 1K files or less. Carefully tuned FS may have better performance for a directory conataining a few thousand files, but no more.
If files are created by some state machine automatically, and you do not have a good sorting algorithm for directory naming, use Year-Month-week for auto directory naming.

This isn't only bound to floating-point intense applications, even the
operating system itselfs seems to suffer from SCHED_ULE. I saw, see and
reported several performance issue under heavy load and for seconds (if
not minutes!) 4+ CPU boxes get as stuck as a UP box does. Those sticky
sitiuations are painful in cases where the box needs to be accessed via
X11.
The remaining four FreeBSD 8.0-boxes used for numerical applications in
our lab (others switched to Linux a long time ago) all uses SCHED_ULE,
as this scheduler was introduced to be the superior scheduler over the
legacy 4BSD. Well, I'll give 4BSD a chance again.
At the moment, even our 8-core DELL Poweredge box is in production use,
but if there is something I can do, menas: benchmarking, I'll give it a try.

Oliver

Hi,
I compared TCP performance between FreeBSD and Linux by running test tools
Netperf and Iperf with Intel NIC.
The kernels are full version and default values are used in the testing
except TCP Congestion Control algorithm set to Reno.
>From the test results we can see Linux TCP performance in throughput is
better than FreeBSD. The worst case (send msg size 128) shows that FreeBSD
throughput is only 43% of Linux's.
I like to get some feedback if anyone did similar comparison test, or knows
any issues with kernels or drivers. Thanks lot.
FreeBSD and Linux Sysctl captures are attached for reference.
Regards,
Hongtao

FreeBSD 7.1 is quite old compared to Linux 2.6.31 - I'd like to see at

Did you compare syscalls made and time taken?
For example, do either/both of them do a lot of gettimeofday() calls?
FreeBSD and Linux have (had?) different behaviours and performance
with those.
I'd suggest digging a bit deeper? :)

There are two gettimeofday calls, one at the beginning of the test and the
other at the end. netperf-2.4.4 is used. I believe gettimeofday is a
vsyscall in linux, but a real system call in freebsd.
Thanks,
Steve

I ran newer FreeBSD code 8.0 RC1 this time. By using NetPIPE, we =
collected
test data and the result shows that FreeBSD TCP performance is worse =
than
Linux. I got troubles to plot using gnuplot, so here I am attaching the =
raw
data files.
The netpipe commands are as follows:
PC2: #NPtcp
PC1: #NPtcp =A8Ch 192.168.1.20

I ran newer FreeBSD code 8.0 RC1 this time. By using NetPIPE, we =
collected
test data and the result shows that FreeBSD TCP performance is worse =
than
Linux. I got troubles to plot using gnuplot, so here I am attaching the =

The netpipe commands are as follows:
PC2: #NPtcp
PC1: #NPtcp =A8Ch 192.168.1.20

There are a few parameters there worth exploring.
For example check the section on net.inet.tcp.sendspace and
net.inet.tcp.recvspace

This is one of the first things we tried.=20

Does anyone have the tuned parameters?=20
=20
Actually we are looking for info like
=20
1. Any bugs in Freebsd driver which have been fixed in linux kernel=20
2. Any TCP features/RFCs implemented in Linux, but not in Freebsd=20
3. Any other discrepancies between Linux and FreeBSD TCP implementation =
that
could potentially have caused this

I see.

It shows that linux default setup is better.

Have you seen any FreeBSD performance tuning guides?

Istvan,

I ran newer FreeBSD code 8.0 RC1 this time. By using NetPIPE, we =
collected
test data and the result shows that FreeBSD TCP performance is worse =
than
Linux. I got troubles to plot using gnuplot, so here I am attaching the =
raw
data files.
The netpipe commands are as follows:
PC2: #NPtcp
PC1: #NPtcp =A8Ch 192.168.1.20

use netpipe TCP pls.

Hi,
I compared TCP performance between FreeBSD and Linux by running test =

Netperf and Iperf with Intel NIC.
The kernels are full version and default values are used in the testing

>From the test results we can see Linux TCP performance in throughput is

FreeBSD
throughput is only 43% of Linux's.
I like to get some feedback if anyone did similar comparison test, or =

any issues with kernels or drivers. Thanks lot.
FreeBSD and Linux Sysctl captures are attached for reference.

That identifies a few other variables which may need addressing. :)

And maybe the wise can send out word of doing well on FreeBSD, so we can
choose a better setup with looking forward repeating the test under
'tuned' conditions? I'm willing to perform some tests within the next 4
weeks when our server hardware (Dell PowerEdge 1950-III with two
if_bge() NICs and 16GB RAM) changes OS from FreeBSD 8.0 to RedHat Linux.
In a time-window of about a week I might be capable of testing FreeBSD
8.0 as it would be that time by the mid of November with a setup of
Linux (distro doesn't matter as I can choose). I need to know WHAT,
WHERE and HOW. Thanks.

Really. Don't post attachments to mailing lists. It's just a bad idea, a
lot of people will be upset with the bandwidth it consumes. Keep in mind
that not everyone on the list is interested in every conversation.

Hi, Steve--

Sure-- put 'em on a webserver somewhere, and put links to them in your
email to this mailing list.
If you wanted to do even better than that, set up a simple webpage
describing what you are doing in your comparison, have a link to the
dmesg/boot output for each platform as a .txt file and a description
of any system tweaks & tuning, have a link that points to a
description of the test setup (ie, your ASCII diagram of the switch
and 4 machines), then your graphs, then the raw data (or links to it,
depending). You can then throw in netstat -s output, or NIC driver
stats from sysctl, or switch stats, etc-- anything else that adds
useful context.
There are a fair number of posts in the list archives which describe
how to benchmark reliably, and the people who are most likely to be
making code changes to FreeBSD also tend to like to know whether
you've collected enough data, in a controlled fashion, to have an idea
as to whether your measurements are reproducible. I'm not a purist,
and I believe you can get useful estimations without rigorous testing,
but there are others who make the point that if you haven't provided
at least a standard deviation, then you haven't collected enough
data-- done enough trials-- to determine whether the results are
meaningful. (See /usr/src/tools/tools/ministat/README)
Of course, you're not obligated to do any of the above, but if you
want the effort you've put in to be more useful, consider these a
suggestion. Finally, the next step beyond that would be to try
tweaking some things, and see what kind of changes you get from that
versus the original performance. It might be the case that making a
simple tuning change would have a significant difference in
performance; if you can identify that, then FreeBSD or Linux
developers can use that information to better tune the OS defaults.
Regards,
