Mnesia Tables to Diskīy default, ejabberd uses Mnesia as its database. If you meet all requirements, you can enable it in this way: erl -s ejabberd +K true.

Passed to the emulator, a warning is issued at startup. If the emulatorĭoesn't have kernel poll support and the +K flag is The kernel poll functionality is disabled. Additionaly, you need to enable this feature while compiling Erlang.įrom Erlang documentation -> Basic Applications -> erts -> erl -> System Flags:Įnables or disables the kernel poll functionality

#Ejabberd mnesia tables mac os

By default, Erlang currently supports kernel polling under FreeBSD, Mac OS X, and Solaris. The kernel polling option requires that you have support for it in your kernel. Hence this option is only interesting on machines that host other services (webserver, mail) on which ejabberd does not receive constant load.Įrl -s ejabberd -env ERL_FULLSWEEP_AFTER 0. Note that this option may downgrade performance. The ERL_FULLSWEEP_AFTER option shrinks the size of the Erlang process after RAM intensive events. ERL_FULLSWEEP_AFTER: Maximum number of collections before a forced fullsweep As these processes are implemented in Erlang, and therefore not related to the operating system processes, you do not have to worry about allowing a huge number of them.Įrl -s ejabberd +P 250000. If there is a lot of activity on ejabberd so that the maximum number of proccesses is reached, people will experiment greater latency times. Maximum Number of Erlang Processes: +PĮrlang consumes a lot of lightweight processes. The option ERL_MAX_PORTS limits the number of concurrent connections and can be specified when starting ejabberd:Įrl -s ejabberd -env ERL_MAX_PORTS 5000.

Erlang Ports Limit: ERL_MAX_PORTSĮrlang consumes one port for every connection, either from a client or from another Jabber server. Remark that some of the described options are experimental. This page lists several tricks to tune your ejabberd and Erlang installation for maximum performance gains.
