A connection pool is there to minimize socket opening overhead. Typically, you do not … Read more
Does linux schedule a process or a thread?
The Linux scheduler (on recent Linux kernels, e.g. 3.0 at least) is scheduling schedulable tasks or simply tasks.

Faster forking of large processes on Linux?
On Linux, you can use posix_spawn(2) with the POSIX_SPAWN_USEVFORK flag to avoid the overhead of copying page tables when forking from a large process. See Minimizing Memory Usage for Creating Application Subprocesses for a good summary of posix_spawn(2), its advantages and some examples. To take advantage of vfork(2), make sure you #define _GNU_SOURCE before #include … Read more
