# TL;DR: A poor-man's full-text search.

Fast/efficient approach:

-- execute("UPDATE posts SET comments_count = (SELECT count(1) FROM comments WHERE comments.post_id = posts.id)")
   -> 1.3197s

Slow/naïve approach:

rmm5t

require 'benchmark'
require 'time'

n = 1_000_000
t = Time.new.utc

Benchmark.bmbm do |x|
  x.report("unix epoch") { n.times { t.to_i.to_s } }
  x.report("iso 8601  ") { n.times { t.iso8601 } }
