But don't all FS accesses (e.g., write to socket, read from DB) require a syscall? In that case, basically all web applications would be affected.
Or am I completely off the mark?
- cortesoft 9y agoNo, you are correct. Really, every application will be affected, they all make some syscalls. How much will vary, though.
- lmm 9y agoAt least one syscall happens at some point, but performance-tuned systems already use "bulk" syscalls where a single syscall can send megabytes of data, check thousands of sockets, or map a whole file into your address space to access as if it were memory.
