his plugin is very nice and works very well...
The peoblens comes when we like to add allot of atributes...
Lets imagine 50 car brands with 100 models each brand equal to 500 records
More 50 moto brands with 100 models each one... more 500 records
If all this is trated as aingle records this can cause overload off all system but if we can use for example...
Atr1 = Car Brand (brand1, brand2, brand3 .... brand 50)
Here instead 50 records we have only 1
Atr2 = Car Model (model1, model2, model3..... model100)
Here instead 100 records we have only 1
On this example instead 150 records we only 2 and if we place this 2 attributes in arrays this can made a huge difference on the perfomance of all system...
Even yesterday i need to increase in php.ini the max_input_vars to 2000 because its not store the values anymore...
Best regards
