If there are 8 core cpu, theoretically OS can write 8 files at the same time with out context switching?
Is there a big difference in speed between writing 8 1gb text files sequentially and at the same time?(using thread or multiprocess)
Solution 1:[1]
Os can open many files and write at a time regardless of the cpu cores but the bottleneck is hard-drive. Even if you have 8 core cpu all of your data that you write have to go sequentially to the hard-drive.
However modern OS don't write directly to files so If you open and write 8 files at same time it is going to stored on RAM and puts in queue for writing to hard-drive so whenever hard-drive gets free it will take that data from ram and write it to the disk.
