Did a product update There were approximately 8000 products in the file Just updated additional fields from the file Minute cron stuck for 8 minutes during update https://baza.cn.ua/admin/shop/statistic/ The panel showed that such a procedure importProductsTaskNew ate 8 minutes of a minute crown. Questions: 1. It is normal that the import of products stopped the work of all minute actions for 8 minutes (this is a question for the ideology of the system, that is, if the import was at 8000, and for example 60,000, then the minute kroner would not work for 1 hour, then it would be lost in general, its logic and name, what kind of minute is it then)? 2.
