             Summary: Consider switching to jemalloc
                 Key: KUDU-1366
                 URL: https://issues.apache.org/jira/browse/KUDU-1366
             Project: Kudu
          Issue Type: Bug
          Components: build
            Reporter: Todd Lipcon


We spend a fair amount of time in the allocator. While we could spend some time 
trying to use arenas more, it's also worth considering switching allocators. I 
ran a few quick tests with jemalloc 4.1 and it seems like it might be better 
than the version of tcmalloc that we use (and has much more active development)
