Hi Lewatle, You may want to review our "Performance Tuning DSpace" best practices related to the frontend: https://wiki.lyrasis.org/display/DSDOC8x/Performance+Tuning+DSpace Specifically, make sure that your have "cluster" mode enabled for PM2. I'd also recommend considering an upgrade to 8.2, as it provides more control over *limiting which pages are processed via server-side rendering (SSR)* (see the "excludePathPatterns" setting). This often provides much better performance for sites, as most of the CPU time is spent on SSR.
