Operating Systems AIX Network Perforamnce - It's just slow! Post 303033114 by hicksd8 on Saturday 30th of March 2019 06:15:04 AM

So you seem to be convinced that this is an ethernet problem. What have you checked?

What about maximum payload configuration? I've seen major issues caused by payload being set to 1502 instead of 1504, for example.
Are some boxes configured to use jumbo packets and others not?
I assume a single chattering ethernet adapter cannot be the issue because the problem is widespread across multiple boxes.
Have you tried putting a wireshark on the traffic to see what's going on?
Do your switches have LED's that tell you what speed has been negotiated?
Have you checked the spec of the ethernet adapters to see what they are capable of?
Stupid question: I assume there is no MS-Windows influence in this at all as they always have network issues with very large files?
Do you have one network device that doesn't handle jumbo packets?

Sorry, more questions than answers I know. Please give more information if you can.

NAME
tv_grab_it - Grab TV listings for Italy. SYNOPSIS
tv_grab_it --help tv_grab_it [--config-file FILE] --configure tv_grab_it [--config-file FILE] [--output FILE] [--days N] [--offset N] [--quiet] [--slow] [--verbose] [--errors-in-xml] [--backend SITE1[,SITE2[,SITE3]]] [--cache-slow] DESCRIPTION
Output TV listings for several channels available in Italy. The grabber relies on parsing HTML so it might stop working at any time. The data comes from different backends. This is to minimize blackouts in case of site changes but also to extend the number of channels. If the grabber can't find the data with the first backend it will try the second one, and so on. You can specify your order of preference using the --backend option. Currently configured backends are (in default order): skylife - grabs data from www.skylife.it mtvit - grabs data from www.mtv.it boingtv - grabs data from www.boingtv.it sitcom1 - grabs data from www.sitcom1.it raisat - grabs data from www.risat.it raiit - grabs data from www.rai.it iris - grabs data from www.iris.it mediasetpremium - grabs data from www.mediasetpremium.it First run tv_grab_it --configure to choose which channels you want to download. Then running tv_grab_it with no arguments will output listings in XML format to standard output. --configure Prompt for which channels, and writes the configuration file. --config-file FILE Set the name of the configuration file, the default is ~/.xmltv/tv_grab_it.conf. This is the file written by --configure and read when grabbing. --gui OPTION Use this option to enable a graphical interface to be used. OPTION may be 'Tk', or left blank for the best available choice. Additional allowed values of OPTION are 'Term' for normal terminal output (default) and 'TermNoProgressBar' to disable the use of XMLTV::ProgressBar. --output FILE write to FILE rather than standard output. --days N Grab N days. The default is 7. --offset N Start N days in the future. The default is to start from today. --quiet Suppress the progress messages normally written to standard error. --slow Downloads more details (descriptions, actors...). This means downloading a new file for each programme, so it's off by default to save time. --cache-slow If you use the --cache option to speed up thing when you grab data several times a week, using this option you will cache only the --slow data, so you shouldn't miss changes in schedules. --verbose Prints out verbose information useful for debugging. --errors-in-xml Outputs warnings as programmes in the xml file, so that you can see errors in your favorite frontend in addition to the default STDERR. --backend Set the backend (or backends) to use. See the examples. --version Show the version of the grabber. --help Print a help message and exit. CAVEATS
If you use --quiet you should also use --errors-in-xml or you won't be warned about errors. Note also that, as opposed to previous versions, this grabber doesn't die if it cannot find any data, but returns an empty (or optionally containing just warnings) xml file instead. The backends' data quality differs a lot. For example, mytv was very basic, yet complete and uses the least amount of bandwith. Skytv has a lot of channels, but unless you use it with the --slow option the data is not very good (and in this case i would be VERY slow). wfactory is a good overall site if you don't need the whole sky package. EXAMPLES
tv_grab_it --backend mtvit --configure configures tv_grab_it using only the backend mtvit tv_grab_it --backend skylife,wfactory --days 1 grabs one day of data overiding the default order (could also be --backend skylife --backend wfactory) tv_grab_it --cache --slow --days 3 grabs the full data for the next three days using the default backend order and using a disk cache. RECOMMENDED USAGE
tv_grab_it --cache --slow --cache-slow --errors-in-xml SEE ALSO
