Presentation by Michał Dykas on how to optimize SSR performance

Michał Dykas and PCG team shared challenges and solutions on reducing lag times when dealing with large repositories in DSpace.

  • PCG team ran into some scalability/performance issues with a large repository.  Currently documented Performance Tuning DSpace instructions were not helpful enough for a large site
  • Developed a way to use Redis for caching (instead of built-in DSpace caching which uses an in-memory lru-cache).  This Redis solution worked well for a large site
  • PCG will donate Redis integration code & also make suggestions on improving documentation.  (This Redis approach would be optional, only for sites that need it.  However for larger sites it can help alleviate the need for a large cluster of node instances
