load testing - JMeter Concurrent Users Count -


i have web application working in production , there 2000+ users of application. have perform performance testing on system there idea how many concurrent users sending requests @ single time? presumed not 2000+ users hit server @ same time.

i going use jmeter load testing of system how many concurrent users should assume must hitting server @ same time?

is there practice being followed in world or varies application-to-application?

any welcomed.

when setting load test setting 3 parameters threads: number of users (threads), ramp period, loop count.

number of threads total number of users have when tests running. can have multiple runs setting loop count test, number of threads never bigger value have set.

ramp period how long can take threads created in seconds. if set example 10 seconds, take time threads created in test run.

loop count affects how many times test repeated.

so if have 100 threads, 0 seconds ramp period , loop count set 1, 100 threads created right away, in case 2000.

i sugest trying out different combinations see how web application handling load. see , undersand better how jmeter creating , executing threads.

i start 100 threads, 10 seconds ramp up, 1 loop, , increase number of threads, decrease ramp period, , increase number of loops.

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
