This curriculum spans the technical and operational rigor of a multi-workshop performance optimisation engagement, addressing the same tuning activities typically handled by internal engineering teams during sustained ITSM platform stabilisation efforts.
Module 1: Performance Baseline Establishment and Metrics Selection
- Select key performance indicators such as incident resolution time, change success rate, and service request backlog growth based on stakeholder SLAs and operational history.
- Deploy monitoring agents on ITSM application servers to capture CPU, memory, disk I/O, and database connection pool utilization during peak business hours. Decide between synthetic transaction monitoring and real-user monitoring for tracking end-to-end service request submission latency across the portal.
- Configure log sampling rates in audit trails to balance diagnostic fidelity with storage cost and indexing performance.
- Integrate APM tools with the ITSM platform to correlate application response times with backend database query performance.
- Establish baseline thresholds for ticket aging by service category to trigger early warnings before SLA breaches.
Module 2: Database Optimization for ITSM Workloads
- Identify and index high-frequency query patterns on incident, change, and configuration tables using database execution plan analysis.
- Partition large historical tables by date range to improve query performance and enable faster archival processes.
- Configure connection pooling parameters to prevent thread exhaustion during bulk import operations or report generation.
- Implement selective denormalization of frequently joined views to reduce JOIN overhead in reporting queries.
- Decide between row-level and page-level locking strategies based on concurrency requirements for change approval workflows.
- Schedule index rebuilds and statistics updates during maintenance windows to avoid contention with user activity.
Module 3: Workflow and Automation Engine Efficiency
- Refactor complex business rules with nested conditions into modular decision tables for faster evaluation and easier maintenance.
- Limit the scope of automated assignment rules by filtering on priority and category to reduce processing overhead.
- Replace synchronous workflow steps with asynchronous job queues for non-critical notifications and data synchronization tasks.
- Cache frequently accessed reference data such as support group hierarchies to reduce repeated database lookups during routing.
- Set timeouts and retry limits on external API calls embedded in workflow scripts to prevent thread blocking.
- Profile automation scripts to identify and eliminate redundant field validation or duplicate event triggers.
Module 4: Integration and API Performance Management
- Implement pagination and field filtering in REST API responses to minimize payload size for mobile and remote clients.
- Use message queuing middleware to decouple high-volume integrations like CMDB population from real-time transaction paths.
- Apply rate limiting and API key throttling to prevent runaway scripts from degrading system responsiveness.
- Cache integration responses for static data such as location codes or approval matrices to reduce backend system load.
- Select between push and pull integration patterns based on latency tolerance and source system capabilities.
- Instrument API gateways to log response times and error rates for SLA tracking and vendor accountability.
Module 5: User Interface and Front-End Scalability
- Optimize portal page load times by deferring non-essential JavaScript and lazy-loading attachment previews.
- Implement client-side caching of user preferences and role-based menu structures to reduce initial session queries.
- Limit default dashboard widgets to those with aggregated, indexed-backed data to prevent long-running queries on login.
- Configure field-level visibility rules to minimize data exposure and reduce payload size in form rendering.
- Compress and serve static assets (CSS, images) via CDN to reduce origin server load for global users.
- Enforce pagination and search filters in list views to prevent unbounded record retrieval in the browser.
Module 6: Capacity Planning and Scalability Architecture
- Model future ticket volume growth using historical trends and business change forecasts to project infrastructure needs.
- Decide between vertical scaling and horizontal clustering based on application licensing, state management, and failover requirements.
- Size application server JVM heap settings to balance garbage collection frequency with response time stability.
- Allocate dedicated search index nodes to isolate full-text search load from transaction processing.
- Plan for read replicas in geographically distributed deployments to reduce cross-region database latency.
- Simulate peak load scenarios using automated scripts to validate auto-scaling policies in cloud environments.
Module 7: Performance Monitoring and Continuous Tuning
- Define alert thresholds for critical metrics such as workflow engine queue depth and failed job counts.
- Correlate performance degradation events with recent configuration changes using change audit logs.
- Rotate and archive performance logs based on retention policies to maintain queryability without storage bloat.
- Conduct quarterly performance health checks focusing on index fragmentation, stale statistics, and cache hit ratios.
- Document tuning actions and their impact to build institutional knowledge and support root cause analysis.
- Establish cross-team review cycles with DBAs, network engineers, and application owners to address systemic bottlenecks.
