Jenkins GUI is slow -removing cookie fixes it (temporarily)

      Jenkins 2.184

      Description

      The last few week/months all our Jenkins users experience very a very slow web GUI after some time. 

      Situation:

      • In a clean browser (no cache, cookies) Jenkins is very fast
      • After some time (workday - 8 hours of active Jenkins use), Jenkins GUI starts to slow down:
        Loading jobs takes 10+ seconds, loading of static resources are very long pending etc.
        Jenkins just isn't workable for users at that time.
      • Logging out + in again does not fix it for that user.
      • Removing the ACEGI_SECURITY_HASHED_REMEMBER_ME_COOKIE cookie fixes everything for that user and makes Jenkins blazing fast again.

       So, what happens with the ACEGI_SECURITY_HASHED_REMEMBER_ME_COOKIE? 
      Why does it cause the slowness after hours of use?

       [update]

       SECURITY-901 / CVE-2019-1003004 in Jenkins 2.150.2 introduced a security fix, but with a side effect that after some time (hours) the Jenkins GUI for that user starts to slow down to a crawl.

            Sverre Moe as you said before, if the "Disable remember me" workaround was not working for you, do not expect this change to work either. It's "just" the correction of the root cause of this issue. From my PoV, wiht all the information you gave, you have another (unknown?) problem that is different from this one.

            Next baseline for sure. 2.176.2 certainly not. 2.176.3 possibly.
