LOAD DATA INFILE & Performance?

Hello,
as Piwik System Checker urged me to activate “Load Data Infile” I did so … but I didn’t notice any Change in Server Load / Performance.
How important is this Option really?

We are tracking about 100.000 PageImpressions / Day

Thank you

It even looks like it hurts performance? See those Spikes in Load Avg. since I activated Load Data Infile … ?

really noone with some insights into this?

if it hurts performance for you, simply disable it
