Description Greg Farnum 2016-07-12 17:45:05 UTC 
Description of problem:
ceph-fuse is being built without being linked to tcmalloc. The default malloc is very bad; a ceph-users report on centos7 says he easily exceeds 10GB of VSS per process, and it is correlated with other issues that are still being pinned down.
(Past experience has shown us that using gmalloc also results in much worse throughput/IOPs in general.)

Version-Release number of selected component (if applicable): Downstream releases based on upstream Jewel, as well as upstream releases. See http://tracker.ceph.com/issues/16655


How reproducible:
It's a build issue.

Steps to Reproduce:
1. Build ceph-fuse
2. Observe it is not linked with tcmalloc


Expected results: ceph-fuse is linked with tcmalloc


Additional info:
Comment 4 Ken Dreyer (Red Hat) 2016-07-14 23:17:46 UTC 
QE team: you can check this link by running "ldd /usr/bin/ceph-fuse | grep tcmalloc"
Comment 5 Yan, Zheng 2016-07-15 01:59:57 UTC 
patch has been pushed into ceph-2-rhel-patches
Comment 9 rakesh-gm 2016-07-25 10:43:14 UTC 
As indicated by Ken, I have run the following command on RHEL and ubuntu,
   
-----ldd /usr/bin/ceph-fuse | grep tcmalloc

and here is the output

------libtcmalloc.so.4 => /lib64/libtcmalloc.so.4 (0x00007fce1a298000)

so moving the bug to verifed stage.
