<https://meetingcpp.com/tl_files/2014/talks/robust_code.pdf> page 34:

Performance of exceptions when not thrown
● Tested on gcc 4.9.2
● Numbers relative to ignoring errors
● With no destructors
    – 12.8% overhead for exceptions
    – 32.8% overhead for return codes
● With destructors
    – 6.3% overhead for exceptions
    – 18.7% overhead for return codes

And page 35:

Performance of exceptions when thrown
● Tested on gcc 4.9.2
● Numbers relative to ignoring errors
● With no destructors
    – 900% overhead for exceptions
● With destructors
    – 750% overhead

Cheers,
Cristian.
