[Bug 2016845] Re: ceph should build linked with tcmalloc

[Alan Baghumian]

I upgraded my "NVME" cluster over the weekend to Quincy (17.2.6) and
thought to post some tests results to compare against the last 16.2.11
and 16.2.13 tests:

17.2.6 (Take 1)

WRITE: bw=144MiB/s (151MB/s), 41.4KiB/s-22.7MiB/s (42.4kB/s-23.8MB/s), io=254GiB (273GB), run=1800932-1807005msec
