I have to wait so long when insert or update Products Module

[angelpeace]

I need your help:

System Version:

$CMS_VERSION = "1.11.10";
$CMS_VERSION_NAME = "Pinzon";
$CMS_SCHEMA_VERSION = "37";

And

Products Module Version: '2.20.3';

I have to wait two minutes when i want to change or add some new products.

I think the reason is (Field Definitions) Type = Image
Everything is ok but it's so long to update product

Please help me to solve this problems.
Thanks!
