Afaik, JBoss > Glassfish or Tomcat.

You could try fine tuning your enterprise application or better still, run a benchmark between JBoss and Glassfish, check the performance between the two in a production environment.

Am sure the test scenario would give you enough insight into performance tuning/upgrading your application to a version closer to JavaEE 6/7+ and a JBoss supported version.

  • thanks...So you are meant to say instead of migrating we could go for fine tuning first. – Suganya Rajeswaran Aug 14 '18 at 05:57
  • Suganya, what I meant to say is you can deploy your App on the latest version of JBoss Wildfly and Glassfish, test/benchmark it for performance, see which part is taking unusually long to execute, ie, database access or "in-between" requests. – Venkat D Aug 14 '18 at 14:47
  • Another *fact* - JBoss Wildfly uses up/requires more memory than Glassfish at the most basic configuration - basically means, no Apps deployed. Like I said, your question could have several answers and not sure SFO allows such 'broad based' discussions. A forum would be a better platform imho. – Venkat D Aug 14 '18 at 15:19
  • Thanks a lot Venkat ji... :) – Suganya Rajeswaran Aug 15 '18 at 10:17
  • And glassfish is full of bugs... i wouldn't even consider it for production. Seems oracle gave it a cold shoulder, and inspired such other servers as `payara.fish` which is based on glassfish but far more stable for production – maress Aug 22 '18 at 08:29
