Hi Aaron,
There is no specific benchmark/table which specifies the performance of universal forwarders. It completely depends on the way universal forwarder is used, if for example a universal forwarder is set to monitor a million directories and options such as "ignoreOlderThan" is not set, UF will have to monitor all the files available.
Other most performance impact is misplacement of wildcard, if a wildcard is specified in that log path and there are other folders which could be matched with the wildcard it would be a performance hit.
Below are few linux command which i use to check the performance of UF
