Before/after memory, swap and cpu usage for scan-build
Hi, so I'm running regular scan-builds with ToT clang against ToT freebsd.
Somewhere between July 27 and July 30 the runtime for these runs increased from
about 15h to more than 30h. The memory usage also increased dramatically,
resulting in clang being killed due to OOM a couple of times during the run.
http://scan.freebsd.your.org/freebsd-head/
the logfile's last-modified dates on that page show you the effective running
time (they all start around midnight UTC).
I also have cpu/ram/swap usage monitoring on that box (it is partially broken,
but it is evident how the cpu/ram usage jumped up at the end of July), see
attachment.
I don't follow the development closely, but I haven't seen any changes in
llvm/tools/clang/tools/scan-build during that timeframe.
