# Summary
#
# After blitzing (via blitz.io) 3 bare bone Rails application that uses 3 different jruby application servers gives
# the following results:
#
# All applications are blitzed using their home url which just render string.
# blitz.io rush rate is 1-250:60 (1 to 60 users doing root url request in 60 seconds)

#
#
# Clearly, given a bare bone rails application, after 3 blitz.io rushing(s):
#
#        - trinidad is the fastest and has fewest errors and not exceeding 512 heroku dyno ram memory
#        - torquebox-lite is second in speed but has 1 error and exceeds 512M heroku dyno ram memory
#        - puma is the slowest and no errors and exceeds 512M heroku dyno ram memory
#
# ALSO, it is worth noting here that amidst the app is just bare bone puma and torquebox-lite keeps on eating so much memory.
