node.js - Heroku Single User Node App, do I need Redis -


i'm building simple node app broadcast messaging using socket.io. have 3 users @ time

user 1: moderator (gets stream of social media comments various apis, picks messages send user 2 , user 3)

user 2: graphics (displays messages pushed user 1 graphics in openbroadcastsoftware)

user 3: host (displays messages pushed user 1 on ipad (to field viewer questions)

this realtime use, nothing needs saved or logged.

i know basics of sending , receiving socket.io messages.

my question is, portability, want host app on heroku

if single free/hobby dyno app, need sort of backend redis? or work if hosting app on local server since there once instance?

this app never going have more 3 users described above, i'm not looking implement scaling what-so-ever

thanks!

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
