Laravel - High CPU utilization after deployment

I'm having serious problems deploying my Laravel application. This is a news site, nothing complicated. The entire homepage is cached in Redis as pure HTML, and query results are also stored in Redis, so MySQL usage is very minimal. The application is fully functional, so we decided to test it in the production environment at night. After deployment, we noticed that the CPU usage jumped to 90-100% on all 12 cores, so the application ran very slowly or not at all. There are about 400 users and 17-20 requests per second. we taste

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
