How to Optimize ServiceNow Performance

ServiceNow is a powerful cloud-based platform used by organizations worldwide to streamline IT service management (ITSM), automate workflows, and enhance business processes. However, as usage grows, performance issues can arise, slowing down response times and affecting productivity. Optimizing ServiceNow's performance is crucial to ensuring it runs smoothly and efficiently. Below are the best strategies to optimize ServiceNow performance and keep your system operating at its best.

1. Efficient Data Management

Large datasets and unnecessary records can slow down ServiceNow. Over time, tables accumulate redundant and outdated records, making queries and reports heavier. To manage this, ServiceNow Training

• Regularly archive old data that is no longer actively used.
• Set up automated clean-up jobs to remove unnecessary log entries.
• Use table rotation for log tables to limit the number of rows.

Tip: Apply filters and conditions to retrieve only relevant records instead of loading complete tables into memory.

2. Optimize Queries

Poorly written queries are one of the leading causes of slow response times in ServiceNow. Optimizing these queries helps in improving performance:

• Use indexed fields in your filters to speed up searches.
• Avoid using the "CONTAINS" operator on large datasets, as it is resource-intensive.
• Leverage database views carefully, as they can cause performance issues when joining large tables. ServiceNow Online Training

Tip: Utilize the “Query Business Rule Profiler” in ServiceNow to identify and optimize slow queries.

3. Minimize Custom Scripts

Custom scripts like Business Rules, Client Scripts, and UI Policies enhance functionality but can slow down performance if overused or poorly written. Here’s how to manage them:

• Consolidate multiple scripts into one where possible.
• Disable unnecessary scripts that are no longer needed.
• Ensure scripts only execute under necessary conditions.

Tip: Limit synchronous scripts on form loads, as they directly impact load times.

4. Use Asynchronous Processing

Whenever possible, offload heavy processes to run asynchronously. This keeps the user experience smooth by not making them wait for background tasks to complete.

• Use scheduled jobs for tasks like data imports or batch updates.
• Utilize "Event Queues" and "Scheduled Scripts" for non-urgent background processes. ServiceNow Course Online

Tip: Offloading long-running processes keeps forms and lists fast and responsive for end-users.

• Minimize the number of related lists on forms.
• Reduce the number of columns in list layouts.
• Remove unused form sections and fields.
• Optimize images and attachments.

Tip: Always test the load time of customized pages to ensure they meet acceptable thresholds.
