Description

Hi 

This is the code to get metadata.  time used is 28 seconds. It's too slow.

It's around 10 seconds if I use HttepoRequest and XML parsing with DocumentBuilder.

Is there anyway to make it faster?

I checked with 5.0.0 and 4.10.0, it's the same.

It seems it does not show nice here, Please check the attached file.

Thank you.
