API request to contents/ is slow #2674

Before submitting an issue to GitBucket I have first:

Issue

Impacted version: 4.35.3

Deployment mode: Tomcat

Problem description:

• accessing the content API call /api/v3/repos/<group>/<repo>/contents with or without ?ref is slow for a large repository

I have a large repository (17k commits, 700MB on disk). The API call to contents/ to the root, which contains 49 objects (dirs and files) takes 10 seconds.

• a call to a directory with 104 entries takes 32s
• 30 entries takes 5s
• 10 entries 2.5s

This also causes a problem with Jenkins, since within the log I see all those calls running into a time out.

I think this is a performance problem in gitbucket, because to me it appears that this call should perform much faster.
