How to optimise this workflow

All,

 

Through various questions  that have been asked by myself and others on the forum, I have created a workflow that can search all the fields for avisible layer with a given search string. The workflow uses the Find Query method on ArcGIS Server which results in a JSON string, which is then processed and the results shown on the map.

 

Can I ask anyone, if they can have a look at the workflow and see if  anything can be optimised even more, i have done as much as my knowledge can go.

 

One issue is the time is takes to process the JSON if there are more than 5 records, it can take up to 30 seconds, which is too long in my opinion.

 

The workflow can be downloaded here

One thing to note is that a custom property called "Search" needs to be added to each layer in GE Manager,

 

Another thing is that I have created this on GE 4.5.1

 

Another thing is i've "stolen" quite alot of code from here, so if you recognise bits of your workflow, within my workflow.. thanks..

 

Thanks
