Answer by Roy Shmuli for Why is printing "B" dramatically slower than printing "#"?

I performed tests on Eclipse vs Netbeans 8.0.2, both with Java version 1.8;I used System.nanoTime() for measurements.

Eclipse:

I got the same time on both cases - around 1.564 seconds.

Netbeans:

• Using "#": 1.536 seconds
• Using "B": 44.164 seconds

So, it looks like Netbeans has a bad performance on print to console.

After more research, I realized that the problem is line-wrapping of the max buffer of Netbeans (it's not restricted to System.out.println command), demonstrated by this code:

    for (int i = 0; i < 1000; i++) {        long t1 = System.nanoTime();        System.out.print("BBB......BBB"); // <- contains 1000 "B"s        long t2 = System.nanoTime();        System.out.println(t2 - t1);        System.out.println("");    }

The time results are less than 1 millisecond every iteration except every fifth iteration, when the time result is around 225 milliseconds. Something like (in nanoseconds):

BBB...31744BBB...31744BBB...31744BBB...31744BBB...226365807BBB...31744BBB...31744BBB...31744BBB...31744BBB...226365807...

And so on.

Summary:

1. Eclipse works perfectly with "B"
2. Netbeans has a line-wrapping problem that can be solved (because the problem does not occur in eclipse)(without adding space after B ("B ")).
