java - Terribly slow on Grails app -


the performance of grails app terribly slow. needs @ least 5-7 seconds load page. prompt me outofmemory , server error 500 every page.

the terribly slow performance affects work , unable test , develop project in acceptable time. have deal problem first.

i tried to:

  1. config settings in idea64.exe.vmoptions , idea.exe.vmoptions settings in development handbook.
  2. config settings of java in java control panel added runtime parameters –xms-4096m.
  3. config settings of %grails_home%\bin\startgrails.bat, grails_opts.

however, situation not improveing.

i using win7-64 bit, 8gb ram, intellij 13.0.2 develop.

please help. thank much!!

this issue database lookup.

out of memory errors caused bringing data (possibly filtering in jvm instead of database query).

slowness possibly caused again bringing data, or n+1 selects
