-----------------------------
Summary: Get metadata of dynamics 365 is very slow, it's much
slower than using HttpRequest
Key: OLINGO-1614
URL: https://issues.apache.org/jira/browse/OLINGO-1614
Project: Olingo
Issue Type: Question
Components: odata2-core, odata4-client
Affects Versions: (Java) V4 4.10.0
Environment: windows, java
Reporter: Yufei
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.
Thank you.
