Exception try catch performance 10 times low than java #12892
Description
A compare test did, result says: performance of try catch throw Exception in .Net is over 10 times slow than in Java.
Reproduce:
C# code
class ExceptionPerformanceTest
{
public void Test()
{
var stopwatch = Stopwatch.StartNew();
ExceptionTest(100_000);
stopwatch.Stop();
Console.WriteLine(stopwatch.ElapsedMilliseconds);
}
private void ExceptionTest(long times)
{
for (int i = 0; i < times; i++)
{
try
{
throw new Exception();
}
catch (Exception ex)
{
//Ignore
}
}
}
}Java Code
public class ExceptionPerformanceTest {
public void Test() {
Instant start = Instant.now();
ExceptionTest(100_000);
Instant end = Instant.now();
Duration duration = Duration.between(start, end);
System.out.println(duration.toMillis());
}
private void ExceptionTest(long times) {
for (int i = 0; i < times; i++) {
try {
throw new Exception();
} catch (Exception ex) {
//Ignore
}
}
}
}Test Result:
.Net: 2151ms
Java: 175ms
2151/175=12.29
