The job config history plugin is infamous for introducing problems in various places (unless you use ramdisk, rarely save changes to config), so this isn't too surprising. 

If you dont' want to remove it (you probably have it for a reason), then there will be a fix coming, and blue ocean shouldn't be slowed down by this either. 

The fix in summary: 

• don't just fetch everything about a pipeline just in case it is needed 
• don't return history data that isn't wanted anyway

One of these should land soon (one is a longer term, one is a shorter term enhancement).

Thanks!

Repoening because the issue is not fixed.

As Marley Kudiabor wrote, the config history plugin did not cause the long loading times.

I am experiencing the exact same issue, opening blue ocean takes 18 seconds for us on a very fast server. Deleting the config history did not help.

I've noticed that the dashboard loads quickly when I'm not authenticated.

Jenkins version 2.46.3, BlueOcean 1.1.2

Hans Schulz it would be better to open a fresh ticket than re-open this one with all the noise as this isn't related to config history plugin (likey another plugin, or number of favourites, could be a lot of things).

Then can chase it down.
