For example when I set a conditional breakpoint on a frequently executed line gdb quickly grows in the order of 500mb per second. When I make the breakpoint unconditional, but add commands to call continue when the condition is not satisfied I still see some big growth, but only in the order of 100mb per second. The difference is probably because breakpoint commands are executed much slower.
