Performance tuning - which tweaks do you make?

Do you set a http or socket keep alive?How about ulimits? Do you increase those?What UV_THREADPOOL_SIZE do you use?Do you disable the idle scavenging part of the GC and trigger it manually (through --expose_gc)?Do you tweak GC in other ways (e.g. by tuning –max-new-space-size)?Do you tweak amount of conns NAT can keep track of (net.ipv4.netfilter.ip_conntrack_max)?Do you tweak memory limits (--max_old_space_size)?Do you rewrite the object keys of JSON to be shorter, to save bandwidth and serialization CPU time?Curious what you experienced Node.js developers have to say about this.
