For example, Microsoft with new versions of MS SQL Server says that the cost of requests decreases, productivity improves and so on (that is, everything is cool), but I have not seen anything like this about new Access.
Actually the question is, is there any development in terms of performance in Access databases or not?
I happened to use 2007,2013,2016 and as they stopped on requests which swallows with a bang MS SQL and stops.
It seems to me that Access still does not exploit the potential of multi-core processors.
Even the allowable size of the database with 2GB does not increase.
