# VST Workers

## Maximum VST Workers

This setting controls how many [VST Workers](../../concepts/vst-worker-pool) should be started.&#x20;

Each VST worker consumes only between 10 and 30 MB of memory when being idle, but this number can raise quickly when the VST worker loads a plugin, especially if the plugin doesn't clean up it's resources properly.&#x20;

PresetMagician will shut down each VST worker after a certain number of loaded plugins to avoid that issue. However, don't set this number too high if you have a limited amount of RAM. For 8GB of RAM, you can use 8 workers.

## Max VST Worker Start Time

This setting controls how long PresetMagician waits until a VST Workers has been started.  If a VST worker doesn't start up within the specified time, it will be stopped.

## Open VST Worker Log Directory

This opens the VST worker log directory in your Windows Explorer.
