And linux has io_uring which can handle millions of syscalls from a single thread without breaking a sweat. In my experience, I/O on Windows is just really slow, every file operation takes 10s to 100s of times longer than on any Unix-like kernel (1000s if windows defender is enabled)
True, but there are also some legitimate applications for 100s of gigabytes of RAM. I’ve been working on a thing for processing historical OpenStreetMap data and it is quite a few orders of magnitude faster to fill the database by loading the 300GiB or so of point data into memory, sorting it in memory, and then partitioning and compressing it into pre-sorted table files which RocksDB can ingest directly without additional processing. I had to get 24x16GiB of RAM in order to do that, though.
