Hi, I'd also recommend looking more closely at your logs to ensure there are no severe errors that are slowing your site down. See our Troubleshooting Guide: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error
Additionally, you should verify that you are following our guidelines for best performance: https://wiki.lyrasis.org/display/DSDOC8x/Performance+Tuning+DSpace Especially take a look at potentially limiting which pages are processed by Server Side Rendering (or make sure you are updated to the latest version of 8.x, currently 8.2). By limiting the pages that are processed by Server Side Rendering, that *may* help to alleviate some of those "greedy bots" that Mark mentions. If you find in your logs (especially your apache logs) that there are some bots that are slowing down your site, we have a ticket where we are starting to gather information about how various sites are blocking or slowing down those greedy bots: https://github.com/DSpace/dspace-angular/issues/4565 You might find some of the hints/tips there useful if this is the problem you are encountering.
