About This “Zimbra Performance Tuning Guidelines for Large Deployments” Webinar:
Zimbra’s wiki, Performance Tuning Guidelines for Large Deployments, is a good starting point, but lacks specific details applicable to Zimbra versions 8.8.15 and Zimbra 9. Further, many Zimbra global, server and localconfig settings have default values that were sensible in their day, but create issues in today’s environment where single mailboxes can reach 100GB or larger.
In this fast-paced, 90-minute webinar conducted by Mark Stone with Panelist John Eastman, VP Client Solutions at Synacor, you will learn:
- How to easily tell if you are CPU, RAM or I/O (disk) constrained.
- IMAP performance enhancements.
- MariaDB memory optimization.
- MTA (Postfix and Amavis) tuning strategies.
- Java (mailboxd) tuning.
- NG Backup disk tuning.
- 60 minutes spent doing the “tune up” work live on a Zimbra Lab Server hosted in Amazon Web Services.
- 30 minutes of Q&A.

What Customers Are Saying
“Our 5,500-mailbox Zimbra system was past end of life and kept freezing up. The team that had built it had moved on and left little system documentation. Mark’s diagnostic skills and performance enhancements enabled us to migrate in stages to a new system with the old system producing 100% uptime and solid performance during the entire migration.”
