How I can optimized the data extraction using perl. That is why I'm creating a script to filter only those informations that I need. Is... (3 Replies)
Need to make a very fast file existence checker. Passing in 20-50K num of files
In the code below ${file} is a file with a listing of +20,000 files. test_speed is the script. I am commenting out the results of <time test_speed try>.
The normal "test -f" is much much too slow when a system... (2 Replies)
I have a script that processes a fair amount of data -- say, 25-50 megs per run. I'd like ideas on speeding it up. The code is actually just a preprocessor -- I'm using another language to do the heavy lifting. But as it happens, the preprocessing takes much more time than the final processing... (3 Replies)

I have some sample code that's supposed to ssh to another machine using Net::SSH::Perl, execute a command, and print
the output of that command. It's very basic, and it works. However, I noticed that upon logging in:
$ssh->login('username','password');
It takes roughly 10-13 seconds to... (2 Replies)

I have "inherited" a OmniOS (illumos based) server.
I noticed rsync is significantly slower in respect to my reference, FreeBSD 12-CURRENT, running on exactly same hardware.
Using same hardware, same command with same source and target disks, OmniOS r151026 gives:

ypinit
YPINIT(8) BSD System Manager's Manual YPINIT(8)NAME
ypinit -- build and install NIS databases
SYNOPSIS
ypinit -m [domainname]
ypinit -s master_server [domainname]
ypinit -u [domainname]
DESCRIPTION
The ypinit utility is a script which sets up databases on a Network Information Service (NIS) master or slave server.
On a master server, ypinit creates the /var/yp/$DOMAINNAME directory, the /var/yp/ypservers file, and calls /var/yp/Makefile to create and
populate an initial set of NIS maps. The maps are created from local source files using the yp_mkdb(8) utility. The utility will prompt the
user for a list of servers that support the specified domain; this list is used to populate the ypservers map.
On a slave server, ypinit creates the /var/yp/$DOMAINNAME, populates it with copies of the NIS maps from the master. The maps are obtained
from the master using the ypxfr(8) utility. The ypinit utility obtains the list of maps to transfer in one of two ways: if the system is
configured as an NIS client and is bound to the master server, ypinit is able to use the ypwhich(1) utility to obtain a list of maps exported
by the master server. If the system is not configured as a client of the NIS master, ypinit uses a hardcoded list of maps, some of which may
or may not actually exist on the master. The system administrator can edit the ypinit script and modify the map list if necessary. Other-
wise, individual maps can be transferred manually from the master using ypxfr(8).
OPTIONS
The ypinit utility supports the following options:
-m [domainname]
Set up a master server. By default, ypinit sets up a server for the system default domain. The user can override this default by
specifying domainname explicitly. Maps are constructed from scratch using local files as templates using the yp_mkdb(8) utility.
-s master_server [domainname]
Set up a slave server using master_name as the master. Maps are copied from master_server to the slave using ypxfr(8). By default,
ypinit sets up a server for the system default domain. The user can override this default by specifying domainname explicitly.
-u [domainname]
Update the ypservers map on the master server. When a new slave server is added to a domain, its hostname must be added to the
ypservers map so that yppush(8) can propagate updates on the master to all of the slaves.
