Subject: experimental speed tweaks:
X-Git-Tag: 1.20~53
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c20b9a6df415e929bb1b3f52473a0b6d641e438b;p=transmission

experimental speed tweaks:
(1) increase the per-peer read buffer to the size of a block message
(2) pulse the peers more often
(3) reduce the tracker delay on startup
