The Hidden Cost Of Exception Handling Grenouille Bouillie Analyzing the cost of exception handling. published on 12 mar 2022. at work, on a very large project, we did something to see how many exceptions were being thrown (and handled, or the software would crash). we were shocked by the results: 110 exceptions per second were being thrown!. Performance cost: exceptions can be expensive in terms of performance, especially if they are used for regular control flow. hidden control flow: exceptions can obscure the normal flow of the program, making the code harder to read and understand. The hidden costs of exceptions. exceptions are designed for exceptional circumstances, not for regular control flows like user input validation or file not found errors. when used as a normal flow. Let’s remove exception handling and replace it with null check so we don’t ask length of null string. list.add(i.tostring()); list.add(null); after this modification the code takes 0.008 seconds to run. it’s roughly taken 570 times faster than letting code fall to exception. so, cost of exceptions can be very high.

Second, with a difference of 100,000 times between empty and complex operations, it does not make much sense to talk about absolute costs of using exceptions. they must be analyzed in the context of operations. the real world: exceptions added. now let’s look at how much the use of an exception costs. the results are shown in table 2:. The true cost of exceptions. here's a short program which just throws exceptions and catches them, just to see how fast it can do it: const int iterations = 5000000; static void main() datetime start = datetime.utcnow; for (int i=0; i < iterations; i ) try. throw new applicationexception(); catch (applicationexception).
