You need to find the reason for the slowdown of the site Tekst ukryty and eliminate it. The site works on UMI.CMS, all sorts of optimizations are made, paid technical support can not help either. There is a problem with a lot of requests for databases and generating garbage. The system cleans some temporary data in the database constantly, if you look at the number of data being added deleted, then the numbers jump +- 50 thousand records within a minute. What to do with it, no one knows.
