In general yes, because the extractors have to be run for every message 
which is processed by that input. The concrete impact varies between 
"negligible" and "a lot" depending on the number and complexity of 
extractors.

I recommend taking a look at the stream_processing_timeout and 
stream_processing_max_faults settings in your graylog2.conf and configure 
them accordingly (or keep the quite sane defaults).


Cheers,
Jochen
