Hi! I`am accessing to Ceph cluster via librados and found that memory usage (VSZ in ps) is extremely increases on writing/reading/removing objects. If I successively write+read+remove the object with the same name, then memory usage is not increased, but if I do the same operations with the different object names then VSZ increases up to 4G and stops at this level. It seems that some internal buffering is enabled, can I configure the maximum size of them? Memory usage is very critical for me and I want to reduce it as much as possible.
Operations write+read+stat+remove in loop with different object names: lion@kubuntu-12:~$ ps aux | grep RADOS lion 7890 0.2 0.0 4289264 3988 ? Sl 10:28 0:00 /home/lion/Projects/RMS/TestRADOS/TestRADOS Operations write+read+stat+remove in loop with one object name: lion@kubuntu-12:~$ ps aux | grep RADOS lion 8149 0.1 0.0 556424 3520 ? Sl 10:30 0:00 /home/lion/Projects/RMS/TestRADOS/TestRADOS Listing of test program: http://pastebin.com/idqt1PEv _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
