I read that you don’t get the file cache, so under what specific
circumstances in linux would it be beneficial to use aio (if any)?

Using AIO under Linux would be beneficial if your working set is
big compared to memory available and as a result filesystem cache
doesn’t improve things much. Better disk concurrency may
outweigh filesystem cache in such cases.
