[jQuery] Joern Form Validation hangs IE when validate monster forms

[jQuery] Joern Form Validation hangs IE when validate monster forms

Hi all.
I have a monster form with more than 110 fields(separeted in tabs) to validate before save in our DB. Every fields need easy validation like:
rules
...
                    pat_ds_veiculo_ano:{required: "#pat_co_veiculos:checked",digits: true, rangeValue:[1905,2008]},
                    pat_vr_veiculo:{required: "#pat_co_veiculos:checked"},                   
                    pat_co_veiculo_alienado:{required: "#pat_co_veiculos:checked"},    
                    pat_dt_alienacao_fim:{required: "#pat_co_veiculo_alienado:checked",dateBR: true},
...
messages
and so on.
But with this validation routine IE hangs and after 6 seconds jQuery shows me(if occured) error message for invalid field.
Looking for workaround I test Jorn example:
<a href="http://jquery.bassistance.de/validate/demo-test/custom-methods-demo.html">http://jquery.bassistance.de/validate/demo-test/custom-methods-demo.html</a>
and insert 100 more fields. Surprise! IE hangs again and validation(error message) occurs after 5, 6 seconds.
Jorn Form Validation is a great great piece of code but looks like doesn't scale for monster form. What's wrong with my form?
Cheers
