For a small number of projects (less or equal to 100) with 1,000 to 5,000 issues in total and about 100-200 users, a recent server (multicore CPU) with 8GB of available RAM and a reasonably fast hard drive (7200 rpm or faster) should cater for your needs. However, if you’re using a 32-bit operating system, you shouldn’t allocate more than 1GB of RAM to Jira. If you’re manually installing/upgrading Jira on a 32-bit system by using the archive, you need to decrease the maximum heap size available to Jira. See the upgrade notes for more information.

Haha, cela répond à ma question précédente 🙂 Jira = 8G de RAM (sans parler de confluence à ajouter) vs wekan à 4Go si ma mémoire est bonne. Bon bah tant pis pour les 20$ les 10 users :).
