By marking this constant, we see approximately 600 symbols become read-only (amd64 GENERIC). While there, also mark the kobj_method structures generated by makeobjops.awk static.

| H A D | ftpd.c | diff 8240 Wed May 03 14:58:12 MDT 1995 wollman Speed up ftpd and make it more efficient: - set TCP_NOPUSH to keep from sending short packets at each write(2) boundary - set SO_SNDBUF to 64k so we have a reasonable amount of buffer space - for a regular file in binary mode which is not being restarted and is . smaller than 16 Meg, use mmap(2) and write(2) the whole file in one big gulp In the most common circumstances, this should dramatically reduce the system-call load from ftpd, since the call to write() will not return until the entire file has been written, rather than writing just a few K at a time in a loop. |
