Is Mmap Faster Than Read at Nathan Johnathan blog

Is Mmap Faster Than Read. If a page of the mapped file is not in memory, access will generate a fault and require kernel to load the page to memory. This can provide significant performance improvements in code that requires a lot of file i/o. Mmap() tends to be slightly faster for random access, read() tends to be faster (or at least, fast enough) for block/streaming access. First, we’ll understand file i/o and standard i/o system calls. I heard (read it on the internet somewhere) that mmap() is faster than sequential io. If yes then why it is faster? Glib buffer for files 3. Reads for sequential data are faster than random reads, for memory mapped data, as well as data that lives on the heap. When reading from file with your own buffering you’ve got 3 levels of buffering overall:
