# The asset preloader is designed to precompute and cache all precompilable

# seeing load times on the order of 10-11 minutes). By preloading, or warming the
# sprockets cache, initial page load times can be reduced to ~15 seconds (with

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:

And, one of my dreams is to talk in rubyconf.
So, I'm very happy and exciting.

# Ubuntu 18.04 and various Docker images such as openjdk:9-jdk throw exceptions when
# Java applications use SSL and HTTPS, because Java 9 changed a file format, if you
# create that file from scratch, like Debian / Ubuntu do.
#
# Before applying, run your application with the Java command line parameter
#  java -Djavax.net.ssl.trustStorePassword=changeit ...
# to verify that this workaround is relevant to your particular issue.
#
# The parameter by itself can be used as a workaround, as well.
