Rsync performance with very large files
We're having a performance issue when attempting to rsync a very large file. Transfer rate is only 1.5MB/sec. My issue looks very similar to this one:
http://www.mail-archive.com/rsync at lists.samba.org/msg17812.html
In that thread, a 'dynamic_hash.diff' patch was developed to work around this issue. I applied the 'dynamic_hash' patch included in the 2.6.7 src, but it

AIX 5.1 rsync large file
Hello,
I have inherited a setup where there are 2 AIX 5.1 systems in 2 separate
sites. There are large database files that are backed from each site to
the other via rsync. Currently, it is using rsync version 2.5.4. It does
it via ssh with the options -avz. This has all been merrily plodding along
for some time. There is one file that is over 45 GB, and it started having
trouble with that

Rsync 4TB datafiles...?
I need to rsync 4 TB datafiles to remote server and clone to a new oracle
database..I have about 40 drives that contains this 4 TB data. I would like
to do rsync from a directory level by using --files-from=FILE option. But
the problem is what will happen if the network connection fails the whole
rsync will fail right.

rsyncing very large files - extremely slow at end
Hello,
I am trying to rsync a tree containing very large files. The first one
encountered is a file that is 127 GB on the remote (authorative) end and
around 80 GB on the receiving end.
rsync version is 2.6.2, patched to fix the bug mentioned at:

But even so transfer is extremely slow towards the end. It will sync

Extremely poor ZFS perf and other observations
I''m observing the following behavior in our environment (Sol10U2, E2900, 24x96, 2x2Gbps, ...)
- I''ve a compressed ZFS filesystem where I''m creating a large tar file. I notice that the tar process is running fine (accumulating CPU, truss shows writes, ...) but for whatever reason the timestamp on the file doesn''t change nor does the file size change. The same is

Feature request for rsync for running scripts
I was wondering if others might find it useful to have a parameter in the
rsync daemon config that would allow running a command on the server at
session start or at successful rsync completion.
For instance, this would allow a webpage to be automatically maintained (by
a script called by this method) with the timestamps of the last successful
rsync completion (no errors, all files transferred),

How do you graph data when you have lots of small values but few extremely large values?
I was thinking of splitting the y-axis into two? Is this possible?
Thanks

Help -- rsync Causing High Load Averages
This is my situation and I am running into dead ends.
We have a server with about 400GB of data that we are trying to backup
with rsync. On the content1 server we had rsyncd.conf as:

path = /
comment = Backup

read only = yes
hosts allow = 192.168.22.181
hosts deny = *

predictive modeling and extremely large data
Hi,
I am new to R and here is what I am doing in it now. I am using machine
learning technique (svm) to do predictive modeling. The data that I am using
is one that is bound to grow perpetually. what I want to know is, say, I fed
in a data set with 5000 data points to svm initially. The algorithm derives
a certain intelligence (i.e.,output) based on these 5000 data points. I

npreg: plotting out of sample, extremely large bandwidths
Hello r-help,
I am using the excellent np package to conduct a nonparametric kernel
regression and am having some trouble plotting the results.
I have 2 covariates, x1 and x2, and a continuous outcome variable y. I
am conducting a nonparametric regression of y on x1 and x2. The one
somewhat unusual feature of these data is that, to be included in the
dataset, x1 must be at least as large as x2.

Dealing With Extremely Large Files
Hi,
I'm sure that a large fixed width file, such as 300 million rows and 1,000
columns, is too large for R to handle on a PC, but are there ways to deal
with it?
For example, is there a way to combine some sampling method with read.fwf so
that you can read in a sample of 100,000 records, for example?
Something like this may make analysis possible.
Once analyzed, is there a way to, say, read

Mode context extremely poor performance.
Hi all,
I curently have a big problem. One request (listed above) using context
take up to 1000 more time than the on RAW or ext2 database. I have ran
this request on a single IA32 machine with Redhat and dbf on ext2. The
average reponse time is less than a sec. The same request on RAC 4 nodes
cluster on RAW take the same average time. On ext2 idem. But on OCFS it
took up to 15 sec randomly

Need Help! Poor performance about randomForest for large data
Hi, dears,
I am processing some data with 60 columns, and 286,730 rows.
Most columns are numerical value, and some columns are categorical value.
It turns out that: when ntree sets to the default value (500), it says "can
not allocate a vector of 1.1 GB size"; And when I set ntree to be a very
small number like 10, it will run for hours.
I use the (x,y) rather than the (formula,data).
