Review request for mesos, Benjamin Hindman, Ben Mahler, Ian Downes, Vinod Kone, and Jiang Yan Xu. Repository: mesos-git Description ------- Master::Http::stats() has performance problem. After profiling (screenshot attached), we found the main cause is due to range addition (e.g. ports resources). Since we don't need to accumulate range resources anyway, I reorganized the code to avoid adding range resources. Diffs ----- src/master/http.cpp ca66d67 Diff: https://reviews.apache.org/r/13433/diff/ Testing ------- make -j4 check File Attachments ---------------- perf profiling results https://reviews.apache.org/media/uploaded/files/2013/08/08/Screen_Shot_2013-08-07_at_3.59.34_PM.png Thanks, Jie Yu
