Soft type versus Hard type performance test?

[hmikic]

Is there any PTC documentation related to Performance Benchmark test - Soft Typing versus Hard Typing ?

[AntonBagryanov]

I guess that performances between soft typing and hard typing are the same and depend only from amount of the attributes and attributes sizes. If type A has more attributes then type B, so A will stored slowly then B.

Hi,

There are not many documents that mark the performance differences between modeled and soft types.

I was able to find some testing that was done on attributes. (see below) (blank shows normal response times)

	Modeled Attribute	Standard Attributes	Global Attributes
Structure Navigation & Where Used	Higher
Folder Listing		Higher	Higher
Create			Higher
Retrieve			Higher
Checkout			Higher
Update			Higher
Checkin	Higher
Delete	Higher

In the Database Modeled Types have their own table as opposed to Soft Types.

The concern being that if you have a lot of Soft Types you may need to check the indexing to ensure the same performance.

Here is an article that I found that mentions using caching to prevent some small performance issue when using many soft type and attributes.

• xconfmanager -p -t codebase/wt.properties -s com.ptc.core.lwc.PrimeTypeCache=true

You can also find the instructions for the Modeled to Soft Type utility in the Customizers guide here:

Hope this helps, and good luck with your implementations!

Thanks,
