Hi,
I noticed when trying to set pgbench's client count to a high number, I had to reduce it, and I found the maximum I can get away with is 1014. Any higher and I get:
invalid number of clients: 1015
I find this in pgbench.c:
#ifdef FD_SETSIZE
#define MAXCLIENTS (FD_SETSIZE - 10)
#else
#define MAXCLIENTS 1024
#endif
And FS_SETSIZE defined before it:
#ifdef WIN32
#define FD_SETSIZE 1024 /* set before winsock2.h is included */
#endif /* ! WIN32 */
... but apparently only if using Windows, which I'm not.
So it appears that MAXCLIENTS is being set to 1014 (1024 - 10), which looks like should only be the case on Windows.
I'm a bit confused here. Shouldn't my MAXCLIENTS be set to 1024?
