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:

xpp_sync
XPP_SYNC(8) User Contributed Perl Documentation XPP_SYNC(8)NAME
xpp_sync - Handle sync selection of Xorcom Astribanks.
SYNOPSIS
xpp_sync <auto|dahdi|nn>
xpp_sync [-v]
DESCRIPTION
On a normal operation one Astribank device provides timing for all the other Astribank devices.
When run without parameters, xpp_sync will display a list of Astribanks (xbuses) that are connected and registered as Dahdi spans. The
current xpp sync master will be marked.
If you this an Astribank is connected and yet it does not appear on the output of xpp_sync, it may be unregistered. Try running
dahdi_registration .
Parameters
auto
Automatically selects the best Astribank for syncing.
dahdi
Gets synchronization from the Dahdi sync master.
nn Sets XBUS-nn as sync source.
-v Also print the numeric xpp sync rank.
(Parameter name is case-insensitive)
Example output:
Setting SYNC
Current sync: 01
Best Available Syncers:
+ XBUS-01 (usb-0000:00:10.4-3) [usb:12345678] [ PRI_TE PRI_NT PRI_TE PRI_NT ]
XBUS-00 (usb-0000:00:10.4-2) [usb:QA-01] [ FXS FXO ]
==================================================
WARNING: FXO which is not the syncer cause bad PCM
Affected Astribanks are:
--------------------------------------------------
XBUS-00
==================================================
In this example we see that the recommended xpp sync master is XBUS-02 - it is the first on the list. It is also the actual syncer, as we
can see from the '+' beside it.
xpp_sync is normally called from the dahdi init.d script. The parameter it is called with defaults to auto, but it is possible to override
that parameter (e.g: set it to dahdi) through the value of XPP_SYNC in /etc/dahdi/init.conf .
FILES
/proc/xpp/sync
(Deprecated: no longer supported) xpp_sync is essentially a nicer interface to /proc/xpp/sync . That file shows the current xpp sync
master (and in what format you need to write to it to set the master).
