Hi @RussellSpitzer, change the test code to use the comparison result. Got
similar perf gain.
```
private void perfCompare(CharSequence str1, CharSequence str2) {
int count = 1_000_000;
boolean result = true;
long start = System.nanoTime();
for(int i = 0; i < count; i++) {
result = equals(str1, str2);
}
long stop = System.nanoTime();
long duration1 = stop-start;
System.out.println("Time: " + (stop-start)/1000000.0 + " msec, result: "
+ result);
Comparator<CharSequence> charSequenceComparator =
Comparators.charSequences();
start = System.nanoTime();
for(int i = 0; i < count; i++) {
result = charSequenceComparator.compare(str1, str2) == 0;
}
stop = System.nanoTime();
System.out.println("Time: " + (stop-start)/1000000.0 + " msec, result: "
+ result);
System.out.println("Duration compare: " + (double)(stop-start)/duration1
+ " times");
}
```
