Just to add. This is not so much related to debugging information in the library files (what gdb can use). That information never makes it from disk so is not that much of a speed issue (esp. if it is split out). It is however related to the debug use flag enabling various kinds of debugging checks, output and whatnot in software. Those tests are useful for debugging, but in the case of tests are normally disabled because of the performance hit they carry.
