It seems that the library does quite a bit of work before filtering away a record, unless the logging is turned off entirely. There's at least two mutex locks, some memory allocation, etc. Callgrind claims ~2500 instructions when the record is thrown away by the global severity filter. Shortened callgrind output is in-line below; full output and the test program attached. Compiled by gcc 4.2.3 using boost.build variant=release threading=multi.
Although I didn't extensively profile the code, I believe that is quite possible.
