apache2 - refreshing browser multiple times causes server to hang -


i run virtual server on apache2 , debian 700mb memmory. noticed after hitting ctrl+f5 multiple times (10 - 15) causes server hang. there no info in logs. plain watching memmory behavior using htop command, can see memmory hit top , swap started rise. takes 3-4 minutes site responsive again. apache2.conf settings :

<ifmodule mpm_prefork_module> startservers          3 minspareservers       6 maxspareservers      6 maxclients           15 serverlimit      15 maxrequestsperchild 500  </ifmodule>

what settings should tweak prevent such hangs? doe's mean, if 10 or more visitors come site, site become unresponsive? goal able serve pages @ least 20 users time. thank you.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
