Laserfiche Forms on DMZ

Forms

Updated November 19, 2015

asked on November 17, 2015

I setup Laserfiche Forms on a customer's DMZ (for the public portal). Everything works fine but I have noticed a long (5+ second delay) before each public form loads. This does not happen with their local install, so it must be something with their DMZ install of Laserfiche Forms.

Attached is a Wireshark log demonstrating the delay between packets when the form is loaded. The full log is attached.

Have anyone seen this issue? What can I do to resolve this?

Thank you,

According to Ajanthan, the behavior is different depending on the URL used. Internal URLs work normally. External URLs are the ones that are slow. This would make it a DMZ rule or NAT issue since they both access the same IIS/Forms machine only through different routes.

If this happens on the first load of the form, it could possibly be the apppool timeout settings are set to the default 20 mins. We had similar performance issues with Forms, but after setting the apppool timeout to "0" in IIS, most issues were resolved. Go into IIS>Application Pools>[Forms App Pool]>Advanced Settings... Under "Process Model" there is a setting called "Idle Time-out (minutes)". Set that value to "0". Now there is another value under "Recycling" called "Regular Time Interval (minutes)" that is default to 1740. You can also set this to "0" but this is optional. I personally would set it to "0" due to first start up performance. Also may want to look into IIS Application Initialization.
