Tomcat HTTP Connections / Threads

Artifactory manages several thread pools. One of them is the HTTP thread pool, which is the number of concurrent incoming HTTP connections Artifactory can handle.
This is configured in $ARTIFACTORY_HOME/tomcat/conf/server.xml. There are separate HTTP connection pools for Artifactory and Access.

Default values:
        <Connector port="8081" sendReasonPhrase="true" relaxedPathChars='[]' relaxedQueryChars='[]' maxThreads="200"/>
        <Connector port="8040" sendReasonPhrase="true" maxThreads="50"/>

Tuning example:
        <Connector port="8081" sendReasonPhrase="true" relaxedPathChars='[]' relaxedQueryChars='[]' maxThreads="1024"/>
        <Connector port="8040" sendReasonPhrase="true" maxThreads="250"/>

*Connector port="8081" is for Artifactory, Connector port="8040" is for Access.
**When updating the Access maxThreads, it is required to update the $ARTIFACTORY_HOME/etc/artifactory.system.properties file with:
artifactory.access.client.max.connections = <VALUE>
