Hello,<\/p>\n

After the last update I suffered a huge impact on the performance of my site. I analyzed the slow queries executed by mysql, and I found that the following function is having a terrible impact on the performance, with queries that need several minutes to be executed:<\/p>\n

Please, consider a system where we have several hundreds or even thousands of events.<\/p>\n
Am I right with this issue? Do you have any solution for this?<\/p>\n
Kind regards,<\/p>\n
