Top Forums UNIX for Advanced & Expert Users Nearly Random, Uncorrelated Server Load Average Spikes Post 303044038 by vbe on Thursday 13th of February 2020 02:58:33 AM
I have seen cases like that when you have enormous disc cache synchronising... all is fine when pure transactional mode ( the periodic sync has hmmm "little" to update ) but when it comes to batches running, it fills the cache before periodic sync and then the system has to wait the end of forced sync (file cache OS side...)
Other contention possible big file cache with big SGA: parsing both and not finding reduces perfs...

Jifty::Script::Server(3pm)				User Contributed Perl Documentation				Jifty::Script::Server(3pm)

NAME
Jifty::Script::Server - A standalone webserver for your Jifty application SYNOPSIS
jifty server jifty server --port 6666 jifty server --stop DESCRIPTION
Starts and stops Jifty's standalone web server. options --port The port to run the server on. Overrides the port in the config file, if it is set there. The default port is 8888. --user USER The user to become after binding to the port. It is advised that you use this when binding to low ports, instead of running as "root". This option only works if the server is using a Net::Server subclass. --group GROUP The group to become after binding to the port. Like "--user", this option only works if the server is using a Net::Server subclass. --host HOSTNAME The host to bind to. This option only works if the server is using a Net::Server subclass. --stop Stops the server, if it is running. This is accomplished by reading the PID from "var/jifty-server.pid" --restart restart the server, if it is running. This is accomplished by killing the child pid, and let parent pid create a new one --sigready SIGNAL Sets the signal number that should be sent to the server's parent process when the server is ready to accept connections. --quiet Reduces the amount of debug output sent by the server --dbiprof Turns on DBI profiling; see DBI::ProfileDumper. --help Print a brief help message and exits. --man Prints the manual page and exits. DESCRIPTION
When you're getting started with Jifty, this is the server you want. It's lightweight and easy to work with. METHODS
run "run" takes no arguments, but starts up a Jifty server process for you. perl v5.14.2 2010-12-08 Jifty::Script::Server(3pm)
