I'm using Bulk Editor, but it's slow. I can increase its speed?
This issue could be due to your server performances (for example Memory limit).
When you load products, the plugin loads all their settings (depending on the enabled columns).
You can improve the plugin performances (by decreasing the requested resources) by disabling the columns you don't need in the Enable Fields modal that is accessible by clicking the Enable fields button in YITH -> Bulk Product Editing -> Products table.
For example we've just disabled all columns, by leaving Title, Description, Regular Price, Sale Price, Categories, Product Type and Date columns active.
This way the requested resources (e.g. Memory) are less and you can load more products at page.
