Why Timing APIs Matter in ServiceNow Development
In a platform as complex and enterprise-critical as ServiceNow, even minor inefficiencies in server-side scripts (e.g., Business Rules, Script Includes, or Flows) can cascade into significant performance bottlenecks. Historically, developers relied on ad-hoc logging or manual timestamp calculations to measure code execution—a tedious and error-prone process. The Yokohama release addresses this gap by bringing standardized timing tools to the platform, enabling precise performance analysis with minimal effort.
 
Breaking Down the New Console Methods
1. console.time(label)
   Starts a timer with a unique label. Use this at the beginning of a code block you want to measure.  
 
2. console.timeLog(label, [data])
   Logs the current duration of the timer without stopping it. Optional data can be appended for context.  
 
3. console.timeEnd(label)
   Stops the timer and logs the total execution time.  
 
These methods work together to create a seamless workflow for tracking performance metrics.
 
​Practical Benefits for ServiceNow Developers
 
1. Pinpoint Performance Bottlenecks
ServiceNow scripts often interact with databases, APIs, or complex business logic. With `console.time()` and `console.timeEnd()`, developers can isolate slow operations.
 
For example: 
console.time("LoadUserData");  
var userData = new GlideRecord('sys_user');  
userData.query(); // Expensive operation  
console.timeEnd("LoadUserData"); // Logs: "LoadUserData: 450ms"  

This instantly reveals whether a query or loop is consuming excessive time, enabling targeted optimizations.  

 

2. Debug Complex Workflows
In multi-step processes (e.g., integrations or approval workflows), `console.timeLog()` allows interim checks without resetting the timer:  
console.time("ProcessIncident");  
fetchData();  // function call
console.timeLog("ProcessIncident", "Data fetched"); // Logs: "ProcessIncident: 320ms: Data fetched"  
transformData();   // function call
console.timeLog("ProcessIncident", "Data transformed"); // Logs: "ProcessIncident: 320ms: Data transformed"
console.timeEnd("ProcessIncident"); // Logs: "ProcessIncident: 780ms"​

This helps identify which phase of a workflow is lagging.

 

3. Standardize Performance Checks
By replacing inconsistent logging practices (e.g., `gs.info("Time: " + new Date().getTime())`), teams can adopt a unified approach to performance monitoring. This consistency improves code readability and collaboration.  
 
4. Optimize for Scalability
In large applications, even small delays per transaction can strain system resources. Timing APIs help developers proactively identify and address inefficiencies, ensuring scripts scale gracefully under load.  
 
Real-World Use Cases
  • Database Query Tuning: Measure `GlideRecord` query times and experiment with optimizations like adjusted conditions or indexes.
  • Integration Monitoring: Track how long external API calls take and set benchmarks for acceptable latency.
  • Script Include Optimization: Identify frequently called functions that need refactoring.  
 
Best Practices
  • Use Descriptive Labels: Assign unique, meaningful names (e.g., `"PortalWidgetRendering"`) to avoid conflicts.  
  • Avoid Overuse: Profile critical paths rather than timing every function to prevent log clutter.
  • Remove in Production: These a​pis are for debugging—strip them from production code or wrap them in debug flags.  
 
Embracing Modern Developer Practices
By integrating `console.time()`, `console.timeLog()`, and `console.timeEnd()`, ServiceNow aligns its scripting environment with industry-standard developer tools. This lowers the learning curve for new developers and empowers teams to adopt data-driven optimization practices.  
 
Conclusion
The Yokohama release’s timing APIs are more than just convenience apis—the​y help us do performance-aware development in ServiceNow. By leveraging these methods, developers can deliver faster, more reliable applications while fostering collaboration through standardized debugging practices.  
 
Start incorporating `console.time()` into your scripts today, and unlock the ability to diagnose, refine, and elevate your ServiceNow solutions like never before.  
 
Optimize smarter, not harder.
