Minor optimization in StandardParser when processing multi-valued metadata with many values #2014
While working on another issue, I detected that the following piece of code in StandardParser class may waste some processing time when dealing with multi-valued metadata with many values, which is not usual, but may happen.
String text = name + ": ";
for (String value : metadata.getValues(name)) {
text += value + " ";
}
In my case, many items have "Communication:To" metadata with ~16,000 values and it takes ~3s in my machine to finish the loop above.
Using a StringBuilder reduced the time to a couple of milliseconds.
