Tableau Server’s performance and stability depend on dedicated resources and proper configuration. Running additional software on the same server is the most likely to cause problems because:
Resource contention: Tableau Server requires significant CPU, RAM, and disk I/O. Other software (e.g., databases, web servers) can compete for these resources, leading to slowdowns, crashes, or failed tasks.
Port conflicts: Tableau uses specific ports (e.g., 80, 443, 8850), and other applications might interfere.
Security risks: Additional software increases the attack surface, potentially compromising Tableau Server.
Tableau recommends running the server on dedicated hardware without unrelated applications.
Option A (Running additional software on the server): Correct. This is a common cause of performance issues and is explicitly discouraged in Tableau’s best practices.
Option B (Separating the Backgrounder and VizQL processes to different machines): Incorrect. This is a supported multi-node configuration that can improve performance, not cause problems, if properly set up via TSM.
Option C (Configuring the server to use a static IP address): Incorrect. A static IP is recommended for Tableau Server to ensure consistent network access, so it’s unlikely to cause issues.
Option D (Using a non-default installation path): Incorrect. While not default, a custom path is supported (via TSM or installer options) and unlikely to cause problems if permissions and disk space are adequate.
