Optimizing Performance in ServiceNow Custom Applications

[aartijangid]

Hi everyone,

I'm currently working on custom applications in ServiceNow and I'm looking for advice on optimizing their performance.Some of the applications I’ve built are starting to experience slower load times and delayed workflows, especially as the amount of data grows.

I'd love to hear from the community about proven strategies and best practices for improving performance in ServiceNow custom apps. What I'm Looking to Learn What are the common performance bottlenecks in custom applications (e.g., scripts, UI policies, client/server scripts, database queries)?

How can we optimize server-side scripts and business rules to reduce execution time?
Are there tips for efficient use of GlideRecord queries and avoiding unnecessary database hits?
Best practices for client-side optimization in ServiceNow forms, lists, and UI pages. Recommendations for indexing, caching, or other database optimizations within Service Now.
How to monitor and measure application performance effectively any tools, plugins, or dashboards?

Please share tips, strategies, real-world experiences, or even sample scripts that helped you optimize performance.
