#5291 closed Enhancement (fixed)

"announce and scrape requests have tiny payloads"

Reported by: reardon Owned by: jordan
Priority: Normal Milestone: 2.80
Component: libtransmission Version: 2.76
Severity: Normal Keywords:


this comment in web.c seems to have come long before multiscrape. The code there sets up a small buf given that announces and single-scrapes are typically quite small. But multiscrapes can be quite large. So I've been using the following optimization in sockoptfunction()

if (isScrape || isAnnounce)
      const int sndbuf = isScrape ? 4096 : 1024;
      const int rcvbuf = isScrape ? 4096 : 3072;
      setsockopt (fd, SOL_SOCKET, SO_SNDBUF, &sndbuf, sizeof (sndbuf));
      setsockopt (fd, SOL_SOCKET, SO_RCVBUF, &rcvbuf, sizeof (rcvbuf));

This should handle scrapes up to ~60 items.

That's a great point. You're correct, that does predate the multiscrape code.

Patched in r14012.
