application is too slow

can someone tell me why this application is so slow? it can literally take up to five minutes to edit existing data.

for example, when i click the 'add' button it takes a minute or two for the 'add' dialog box form to pop up.

it then takes another minute for the application to acknowledge you hit the 'submit' button.

and it then takes another few minutes for the changes to actually take affect. and sometimes the changes never take affect but instead pop un an error message.

i love zoho creator but this issue makes it almost unusable at times. unfortunately i've got too much data and time invested in it to switch to a different platform.

maybe my application is just to big or i have too much data. either way, please tell me if this is the case or anything i could do to speed things up!

thanks.
