The Linux kernel maintains data structures to track a processes' open file descriptors, and it expands these structures as necessary when FD usage grows (at every FD=2^X starting at 64). However when threading is in use, during expansion the kernel will pause (observed up to 47ms) while it waits for thread synchronization (see https://bugzilla.kernel.org/show_bug.cgi?id=217366). This change addresses the issue and avoids the random pauses by opening the maximum file descriptor during initialization, so that expansion will not occur while processing traffic. |
