When viewing the plug-in manager there is an information pane at the bottom which displays the latency for each plug-in.
What is that number a measurement of? Samples?
Does latency stack (in serial?) from multiple instances of the same plug-in, or does the total latency remain the same with multiple instances (in parallel?)?
Put another way, does the total latency added by plug-ins come from adding all of the latencies together (including multiples for each instance), or is the total latency represented by the plug-in with the highest latency measurement?
