Hunting down a session serde problem, it was painful having to wait almost a minute between clicks for the application to settle down and stop showing the blue scrollbar. Is there anything that can be done to make this useful again?

Also, from the output you see that one sessions serde times out at 30000ms but all the others complete succesfully at 40 seconds or more. Does that indicate a bug perhaps ?

Serialization should not take so much time.
I remember there were a couple of fixes related to performance some time ago.
One reason could be that the serialization process cannot obtain the VaadinSession lock because of other process locking the session.

Can the session lock wait time be made visible in the logs somehow ?

SessionSerializer logs at TRACE level failed attempts to perform optimistic serialization

here is some more output then:

At a first look, it seems you are running debug serialization along with "production" serialization. So at the end of the request the session might be serialized both by the debugger and the servlet filter, causing locks to be held.

Also, looking at some of the serialization requests, it seems timings can be very different for the same session size

To better investigate, could you please run the application only with the debugger serializer on and check if the process is still so slow?

I have disabled the redis serialization, but it does not make a difference.

Could you please attach the logs with redis backend disabled?

It looks like most of the time is spent in deserialization.
Could you please activate TRACE level only for the following categories (to make it easier to inspect the logs)?

com.vaadin.kubernetes.starter.sessiontracker.serialization.TransientInjectableObjectInputStream=TRACE
com.vaadin.kubernetes.starter.sessiontracker.serialization.debug=TRACE

@jorgheymans can you briefly describe how the UI is made up?
From the logs I can see that the for first two requests the deserialization is quite fast, but the third request takes a lot.
In that deserialization I can see a big graph (more than 65000 entries tracked counting objects and class descriptors) and it seems objects are inspected several times. For example, I can see 861 entries for TranslatedCodeListItem, 179 for SpringBasedBeanValidator.
I guess it could be a combination of Grid and forms.

Another thing that makes me wonder is to see an entry for SpringServlet, that should not be serialized.

That particular screen is 12 tabs, each with a dozen standard input fields and/or CrudGrids. There's a lot of reference data being loaded (the TranslatedCodelistItems). 179 SpringBasedBeanValidator instances seems wrong, there should not be more than about 20. We don't knowingly serialize SpringServlet though, how could it end up there?

Did you already try to restrict the packages inspected by transient handler to see if it helps?

Yes, as per documentation it's set to the root package of our application.
