Operating Systems Solaris Solaris 11.1 Slow Network Performance Post 302826013 by Just Ice on Tuesday 25th of June 2013 04:10:22 PM

you may be right about the loopback but i cannot say for sure as i do not have access to those kind of machines -- maybe somebody else here can explain further ...

you may also want to see the configurations of the appropriate network devices on your other solaris servers and their appropriate ports on the switch if they are able to send the big files much faster ...

btw, i had my network group actually hard set the affected ports on the switch to run 100/full so my servers' network ports were not continually auto-negotiating ... the standards at that company was also to set every network port to auto but they had to make an exception for my production servers ...

if your network group balks at the request to hard set the ports, call up oracle support to see if they have better ideas if nobody else here has one ...

NAME
foomatic-getpjloptions - <put a short description here> SYNOPSIS
foomatic-getpjloptions device foomatic-getpjloptions hostname port DESCRIPTION
foomatic-getpjloptions Sends a set of PJL commands and reads back the PJL options and status from a printer over a network connection or device bidirectional interface such as parallel, USB, serial. printers to standard output. The output can be piped into foomatic-addpjlop- tions to add options to the database. Options device The interface to which a local printer is connected, e.g. /dev/lp0, /dev/usb/lp0, /dev/tty00, etc. For a parallel port, you must have bidirectional support enabled at the BIOS level and the parallel port driver must support the bidirectional mode. Check your parallel port BIOS settings for EPP/bi-directional mode. hostname Host name or IP address of a network printer (HP JetDirect, DLINK, etc.). port Port on which your network printer listens for socket (Appsocket) connections. Most common ports are 9100 (JetDirect), 10000 (DLINK). Usually you can configure the port via a configuration interface. EXIT STATUS
foomatic-getpjloptions returns ??? AUTHOR
Manfred Wassmann <manolo@NCC-1701.B.Shuttle.de> for the foomatic project using output from the associated binary. Modified by Patrick Pow- ell <papowell at lprng.com> to provide betters support for network printers, error messages, and remove CR and FF from output. WARNINGS
Uni-directional protocols as remote LPD are not supported as no status is returned. Some network print servers which attach to a printer parallel port do not support bidirectional mode. Foomatic Project 2001-05-07 FOOMATIC-GETPJLOPTIONS(8)
