Quote:

Allocator-based serialization for (Re)Actors is extremely fast (for x64 – around tens of ms per 100MB of state)

Another Quote:

Per-(Re)Actor allocators can be implemented without any changes within (Re)Actor itself (i.e. all the necessary changes can be confined to Infrastructure Code).

Quote:

with std::reduce() such code, while it compiles at least under MSVC, MAY occasionally provide wrong results

Another Quote:

if you happen to need something beyond that – take a deep breath and allocate at least several months to understand how does parallelism really work under the hood.

Quote:

as long as serial code provides good-enough response times from end-user perspective – DON’T PARALLELIZE

Another Quote:

out of all the premature optimizations, premature parallelization is the most premature one

Abstract:

I made an experiment which demonstrates Big Fat Dangers(tm) of implying that parallelization can be made as simple as just adding a policy parameter to your std:: call.

it is still necessary to understand what we’re doing
