Troubleshooting two different Models showing same data

[#1]

Hi,

I have two different model which reflects same set of data.

They are originating from different Databases.

One set is based on QVD which are created in 10 minutes through a mySQL partitions import.

Set Two is based on QVD which are created in over 100 minutes through a regular mysql.

Set one when loaded to a QVW provide nice response time.

Set two when loaded to a very simillar QVW (some adaptation needed) is responding slowly. Its a pain to work with.

Is there a way I can "troubleshoot" what is the cause of the slow response time ?

Can I "see" what slows things ?

Thanks
