#3051 closed Enhancement (fixed)

Faster startup by adding "have all" idiom to resume files

Reported by: charles Owned by: charles
Priority: Normal Milestone: 2.00
Component: libtransmission Version: 1.92
Severity: Normal Keywords: performance


According to valgrind's "cachegrind" profiler, the most expensive CPU use during Transmission's startup -- by far -- is reading and processing the torrents' bitfields from the resume file.

If people are using Transmission with dozens or hundreds of torrents or even more, it's very likely that most of these torrents are complete. If we were to add a "have all" tag to the resume file, we could avoid all this overhead.
