Muting the ARRANGE track (or audio region on it) will stop reading audio from disk and any plugins will use no CPU - if there's no audio passing through a plugin, in theory Logic ensures it uses no CPU (true for most, but not all plugins). This mute takes a little time to happen. Bypassing a plugin (bypass button or option-click the insert slot) should also free the CPU. This can also take a little time, depending on the plugin. Muting the MIXER channel will still be processing prior to the mute, so will not free any CPU (and will be instant).
