Subject: [PATCH] Performance: Increase database buffer pools for Nextcloud and
 Zabbix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Nextcloud MariaDB: 128MB → 4GB buffer pool
- Zabbix MariaDB: 128MB → 3GB buffer pool
- Added innodb-log-file-size=512M for better write performance
- Added max-connections=200 for better concurrency
- Created performance.cnf for Zabbix with additional optimizations

Expected improvement: 3-6x faster database queries
Impact: Better responsiveness for Nextcloud and Zabbix web UI
