performance problems with drop down list and repeating table

[smnbss]

I've a repeating table that use some drop down list with lookup value
for populate some fields, but when i've more than 20 rows in my table,
infopath improve about 20 seconds to load the interface.

Is this normal ?

Someone have an idea to speed up the user interface ?

i've 3 DDL for each detail row

first DDL : 181
second DDL : 868
third : 174

I know it's a bit too much, but i'm going to think that infopath is
good only for demo project...
