I have a document with ~200 references. Some of the author fields are rather large. With Biber 2.7 a biber run took about 5-10 sec. With Biber 2.8 this takes now ~3 min.

Are their new features or options in Biber 2.8 / biblatex 3.8a which could cause such a behaviour and could be turned off?

How could I tell biber to truncate long author fields before processing it?

Here's a MWE:

    I get 11 seconds, but it's long time nonetheless. And I get 1.6 seconds with Biber 2.7. Mac OS X Sierra here.

    Yes, this is the case - there is a new system for tracking uniquename which saves the information needed for arbitrary name parts. This was needed to complete name generalisation. I consider such cases edge cases as that's a huge name list which needs disambiguation markers saving for every name position. If you want to speed it up during document development, just put in a source map to truncate name lists to one or two names until you want to run the final compile. I can't really help this - bibtex does about do 20% of what biber is doing.

    Ok, I have run a code profiler on this name list beast example and I see perhaps some optimisations. Since I have to release 2.9 soon anyway due to a tool mode bug, I think something can be done. Watch this space.

    @luki Workaround: As your author list is already incomplete (marked by and others at the end), you could simply delete all but the first few authors. Nov 18 '17 at 12:46

    I have just updated 2.9 DEV again. I found a huge optimisation which means that even with uniquename enabled, this shouldn't be bad now. On my machine, it reduces the time with this example and uniquename enabled from 5 mins to 14 seconds.

As a workaround during document development the author field can be truncated to a single author with a source map.
