The 'throttleConnectorStartup' property can be enabled(set to '1') in the %SOI_HOME%\resources\Configurations\SSA_IFW_HostName.xml file
This option defines whether to initialize connectors on the system simultaneously or one

You can change this setting to 1 for connectors to initialize sequentially, which
can improve the performance. The setting can also prevent memory overuse if
there are multiple connectors on the system that manage large amounts of CIs
