Script execution usage limit exceeded

Hello,

Is there a any change to round this issue?

I have a customer that wants to split work order with quantity of 60 to 60 of work orders with quantity of one.
I made a client script that is executed from custom buttom.
Everything works fine, but after creating 33 new work orders Script execution usage is full and scripts stops.
I't doesn't make a rollback, it just stops.

Is there any way to write more effectice script that uses less usage units?

My Script :

function splitwo()
{
    var id = nlapiGetRecordId();
    var WOrec = nlapiLoadRecord('workorder',id);
    var count = WOrec.getFieldValue('quantity');
    var newcount = count-1;
