Description:
https://dev.mysql.com/doc/refman/5.7/en/optimizing-innodb-logging.html

The first paragraph reads:

"Make your redo log files big, even as big as the buffer pool. ...  Although historically big redo log files caused lengthy recovery times, recovery is now much faster and you can confidently use large redo log files."

But variable description in https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_log_file_size reads:

"Larger log files also make crash recovery slower."

Which one is right?

How to repeat:
Read documentation
