How to test web application performance ? -


we have web application (uisng asp.net , alaska waa) designed many years ago (not team). uses alaska’s xbase++ code via waa query database , generate html response. earlier running on win 2003 , iis 6. web application migrated new environment .. windows 2008 , iis7 (we did migration).

this application uses mysql backend , shows images stored in shared drive. problem website’s performance not satisfactory. pages taking more 10-12 sec load (which not case earlier setup). now, want track down down root cause of delay. suspecting performance of db server , shared drive. how can confirm ? there tool can track down cause ths delay ? (alaska waa – web application adapater—it kind of application server run xbase++ code on server. iis request waa (like cgi application) , waa server side processing.. getting details db, generate html response , retun iis) or xbase++ code base huge , cannot go through code fine tune queries. there way test db server performance, shared drive performance, cgi performance.. ?

first question whether new platform windows server 2008 , iis 7.0, or perhaps windows server 2008 r2 iis 7.5. there notable file performance issues in windows server 2008 , these may contributing performance issues result of migration. migrating windows server 2008 r2 (if that's not are) may enough resolve these issues.

however, within realm of tools can isolate location , causes of web performance issues, may find value our web performance monitor. 30-day free trial available, , may sufficient isolate , resolve issue.

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
