Zhao Yongming commented on TS-1822:
-----------------------------------
we make use of the reclaim freelist on our 48G memory system, handling about
24-32G ram cache, with about 32KB everage content size, the default sysctl
seting "vm.max_map_count = 65530" is no enough, we have to rise it to 2x.
so, I'd make this a option to rise the default sysctl setting if we choose to
keep it, for example by cop process.
> Do we still need proxy.config.system.mmap_max ?

> A long time ago, we added proxy.config.system.mmap_max to let the
> traffic_server increase the max number of mmap segments that we want to use.
> We currently set this to 2MM.
> I'm wondering, do we really need this still ?
