Where I were mostly moving stuff around in HOL. This should be only visible
in Complex_Main and not in Main. But the HOL-Proof and especially the
ZF images also take more time.

I don't see anything suspicious in that range -- apart from theory names in plural, which potentially violate the usual naming conventions, unless there are reasons for that (i.e. multiple related concepts defined.)

When you define a theory of real vector spaces, it would be called Real_Vector_Space by default. A counter-example is theory Numeral_Simprocs, which defines various numeral simprocs.

I talked to Johannes and this slowdown doesn't seem to be related to his changes from 26.3. One can also see here that almost all sessions started to take more time to be built around that time:
http://isabelle.in.tum.de/devel/stats/at-poly.html

at-poly is just one of many tests. There is no change in most others, e.g. http://isabelle.in.tum.de/devel/stats/mac-poly-M2.html

So it could be just a fluctuation of local machine configuration (one of the many OS updates that the admins did recently or some changes of shared libraries), or changes of the concreye Poly/ML compilation being used.

Since the isatest settings are visible in Admin/isatest/settings within the repository, and there is no recent change to be seen, I would guess at some effect from OS or file-system / file-servers at TUM.
