[ovs-dev] [PATCH] Add --enable-jemalloc argument to build

[Huang, Lei]

Hi,

I tested the patch in our scalability test environment, the test case as blow:
- 1000 sandboxes are created
- Each time create 5 lswitches each has 200 lports, that is, 1000 lport in total, then bind lports one by one to sandboxes randomly

After linked ovsdb-server, ovn-controller with jemalloc, the case running speed is faster about 10%:

lport        bind 1k ports time(in seconds)
number(k)    without jemalloc    with jemalloc

6            1218.208           1066.675
7            1245.089           1085.023
8            1265.645           1124.438
9            1260.462           1105.621
10           1229.317           1103.637



So I suggest this patch should be merged into mainstream.
