issue of dataTable with huge amount of data input

[Daniel Leung Leung]

Dear all,

I am now using Websphere6.1 with JSF RI 1.1 for my development

I have a program for user to input results of each student. I am using dataTable to make the table of students (around 30 students) with result inputboxes of different subjects (around 10 subjects).

But, when I submit the page, it is quite slow (around 30sec. needed to next page). I found that the process is very fast in Update Model Values Phases, Invoke Application Phase and Render Response Phase. And, I haven't implement any validation in page. I think the main bottleneck is at Restore View Phase and Apply Request Values Phase. I am wondering if huge amount of data input at dataTable will cause performance issue.

Did anyone meet the same problem before? Please help. Thanks.

brgds,
Daniel
