How do I increase the CPU time limit in Salesforce?
What To Do If You Keep Exceeding Apex CPU Time Limit?use more optimized loops.use bulkified triggers patterns.move some logic to future methods.avoid nested loops where it is possible.move aggregation to SOQL where it’s possible.
How is maximum heap size calculated?
Calculate Maximum Heap Size:Weekday load during business hours: Peak web page load of 4 GB + Asynchronous message processing of 2 GB = 6 GB.Weekend load at night: Regular web page load of 0.5 GB + Weekly report generation of 4 GB + Nightly batch processing of 1 GB + Asynchronous message processing of 2 GB = 7.5 GB.
What is CPU time limit in Salesforce?
10 secondsFor insert and update operations, Salesforce limits the amount of CPU time to 10 seconds. This may seem like plenty of time but this quota can quickly be eaten up by inefficient triggers, Process Builder Flows, and more. A key concept to understand is that this limit is shared by all Apex code executing.
