I realize that for some strange reason the "xx_products.php" file get big file size. I open the file to an editor and i saw thousands of lines including this pattern
At this moment the file has a size almost 2 MB. I delete all this lines and now the file has a size of only 70KB!!!!!!!
I add some new products and i realize that the sile size change again. I open once again the file in my editor and i saw once again the pattern (although now there are just a few lines). After editing or adding new products, there are more and more lines.
Any ideas why this happen or a way to prevent this happen?
The first solution (update) is not an option, for many reasons. I read a couple of times the document you suggest but i can't find anything related with my question.
