PS1, Line 316:           such as the number of cores and number of threads involved in the query.
State explicitly that slowdowns of up to 30x have been observed for scan-heavy queries. I think that was ultimately the ask of the users.

I think it's also important to re-iterate that the setting only has effect for files generated by Hive. For Impala generated files this setting has no effect or slowdown.
