# Jetty thread settings

To change the Jetty thread pool settings, add the following excerpt to your project's `conf/config.properties` file:

```none
# Jetty maxThreads (default 200)
org.ops4j.pax.web.server.maxThreads=${org.ops4j.pax.web.server.maxThreads}
# Jetty minThreads (default 8)
org.ops4j.pax.web.server.minThreads=${org.ops4j.pax.web.server.minThreads}
# Jetty idle-thread timeout milliseconds (default 60000)
org.ops4j.pax.web.server.idleTimeout=${org.ops4j.pax.web.server.idleTimeout}
```

To override these defaults, set a corresponding `OPENIDM_OPTS` variable when you start IDM. For example:

```
export OPENIDM_OPTS="-Xmx1024m -Xms1024m -Dorg.ops4j.pax.web.server.maxThreads=768" /path/to/openidm/startup.sh
Executing ./startup.sh...
Using OPENIDM_HOME:   /path/to/openidm
Using PROJECT_HOME:   /path/to/openidm
Using OPENIDM_OPTS:   -Xmx1024m -Xms1024m -Dorg.ops4j.pax.web.server.maxThreads=768
Using LOGGING_CONFIG: -Djava.util.logging.config.file=/path/to/openidm/conf/logging.properties
-> OpenIDM version "7.2.0-SNAPSHOT" (revision: unknown)
OpenIDM ready
```

|   | You cannot use property substitution to set these properties.You cannot adjust Jetty's thread settings in the `conf/jetty.xml` file. If you uncomment the excerpt of `jetty.xml` that starts with `<!--<Arg name="threadpool">...`, you'll see errors in the IDM log. |
