Look at this piece of code:
MessageParser parser = new MessageParser();
for (int i = 0; i < 10000; i++) {
parser.parse(plainMessage, user);
}
For some reason, it runs SLOWER (by about 100ms) than
for (int i = 0; i < 10000; i++) {
MessageParser parser = new MessageParser();
parser.parse(plainMessage, user);
}
Any ideas why? The tests were repeated a lot of times, so it wasn't just random. How could creating an object 10000 times be faster than creating it once?
