<ig:gridView> has performance problems
posted

Hi,

I am encountering a big performance problem with the <ig:gridView> as compared to the <h:dataTable>, or to the <t:dataTable>.

We have used JProfiler to measure the response time of a request to a JSP which renders 15 rows of a simnple POJO,
including passthrough a service layer (EJB), and a data layer (hibernate).

The results were as follows:

<t:dataTable> - 900 Milliseconds
<ig:gridView> - 2000 Milliseconds

How to reproduce:

1). Create a JSF managed bean with a getter method to a List which holds 15 POJOs.
2). Create a JSP file with a <t:dataTable> which renders the 15 POJOs as rows.
3). Create a JSP file with a <ig:gridView> which renders the 15 POJOs as rows.
4). Compare the 2 pages' response times.
