Description:

when starting Jenkins, it loads all jobs which eventually trigger a parse of the whole build history. That definitely takes a long time and cause my setup to take up to 20 minutes to start.

Using jstack, I found out stack traces such as:

For a freestyle project:

"Loading job mwext-VectorBeta-lint" daemon prio=10 tid=0x00007f8a24001000 nid=0x33c0 runnable [0x00007f8a8854e000]

Or in a maven project:

"Loading job gerrit-core-wmf" daemon prio=10 tid=0x00007f8a08001000 nid=0x33c5 runnable [0x00007f8a03ffd000]

Using strace, I can confirm Jenkins attempt to load all the build history files I am not sure why it would need to do so though.
