CPU time
CPU time (or process time) is the amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program or operating system, as opposed to, for example, waiting for input/output (I/O) operations or entering low-power (idle) mode. The CPU time …
. Try using more code blocks instead of doing too much in a single set of nested loops. Recursion.
What is the CPU time out limit for @future in Salesforce?
If there is a chance to make code execute in @future ,this will break the context and also the CPU time out limit for asynchronous process is 60seconds(6X of synchronous process). Consider this if you’re at risk of hitting the limit. Aggregate SOQL usage
Where does the CPU time error come from in Salesforce?
The CPU time error is contained within Salesforce Governor Limits. Let’s dive into the specifics of this, why it’s important, and how we debug it… First of all, what are Salesforce governor limits?
Why is there a CPU time limit in apex?
Common Reasons Encountering “Apex CPU Time Limit” One of the common reasons we hit the CPU limit is that the trigger logic enters unexpectedly multiple times. Trigger logic finishes first, workflow follows to update the record which then causes the trigger logic to re-enter.
Why is there a CPU time limit on my Trigger?
Common Reasons Encountering “Apex CPU Time Limit” One of the common reasons we hit the CPU limit is that the trigger logic enters unexpectedly multiple times. Trigger logic finishes first, workflow follows to update the record which then causes the trigger logic to re-enter. Another reason is the trigger custom code logic itself.
Can we increase CPU time limit in Salesforce?
However, Apex CPU Time Limit is an exception. It is non-negotiable. This means we cannot increase the 10-second threshold by tweaking settings, buying more allocations from Salesforce or work around it by other means. It is an absolute hard limit.
Why is CPU time limit exceeded in Salesforce?
Salesforce limits CPU usage to 10 seconds for synchronous transactions and 60 seconds for asynchronous transactions. Seeing the error “Apex CPU time limit exceeded” means your transaction is taking too long and can’t be completed. It’s also likely a signal of greater problems in your system.
How do I reduce CPU 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.
What is CPU timeout in Salesforce?
Description. Salesforce has a timeout limit for transactions based on CPU usage. If transactions consume too much CPU time, they will be shut down as a long-running transaction. Resolution. We only count events that require application server CPU use.
How do I reduce CPU time limit exceeded in Salesforce?
If you’re hitting Apex CPU time limit exceeded errors, the quick, relatively easy fix includes:process your manual inserts in smaller batches.schedule your automation to run only when and where needed.control your batch size in automated updates.
What is the transaction limit on max Salesforce CPU time?
Salesforce limits CPU time for every transaction to 10 seconds. This limit is shared by all processes running in the trigger code, so Apex CPU timeouts are a group effort.
What is heap size limit in Salesforce?
Salesforce enforces an Apex Heap Size Limit of 6MB for synchronous transactions and 12MB for asynchronous transactions. The “Apex heap size too large” error occurs when too much data is being stored in memory during processing.

How do I catch a limit exception in Salesforce?
try to use getLimitQueries() and getQueries() to determine how many rows you can query, and add LIMIT statement to your soql, and in case if amount of the records is same as limit — put error message (or warning ). Trick is that you can not catch limit exception — like CPU time, DML or SOQL amounts etc.
What is the transaction limit on the max timeout for all callouts?
120 secondsThe maximum cumulative timeout for callouts by a single Apex transaction is 120 seconds. This time is additive across all callouts invoked by the Apex transaction.

Why are nested loops so slow?
For example, nested loops can be very slow when processing a large volume of records. The last but not least reason is the code in the managed packages. This is, unfortunately, a BlackBox, if the code in a managed package consumes too much time, you need to reach out to the vendor for assistance.
Is the 10 second threshold a non-negotiable limit?
It is non-negotiable. This means we cannot increase the 10-second threshold by tweaking settings, buying more allocations from Salesforce or work around it by other means. It is an absolute hard limit. It shuts down the execution immediately.
What is a CPU timeout error?
Salesforce limits CPU usage to 10 seconds for synchronous transactions and 60 seconds for asynchronous transactions. Seeing the error “Apex CPU time limit exceeded” means your transaction is taking too long and can’t be completed. It’s also likely a signal of greater problems in your system.
Optimizing to Avoid CPU Timeout Errors
There are two primary situations in which a CPU timeout will occur. The first is that your processes are simple, but you’re processing too many records at once. In this case, the record count alone will force your code to hit the processing limit.
Automation Best Practices

About The ‘Apex CPU Time Limit Exceeded’ Error
-
Salesforce has a timeout limit for transactions based on CPU usage. If transactions consume too much CPU time, they will be shut down as a long-running transaction. CPU Timeout Governor Limit: 1. Synchronous Process: 10 seconds 2. Asynchronous process: 60 seconds Note: If you started getting ‘Apex CPU time limit exceeded’ error in production and if…
How to Reduce CPU Timeout?
- 2.2. Asynchronous Processing
CPU time out limit for asynchronous process is 60seconds(6X of synchronous process). If the results of the operation are not required in real time consider moving logic to asynchronous processing. Asynchronous processing comes in a number of different flavors. - 2.3. Aggregate SOQL
Database time is not calculated in CPU time. Using aggregate SOQL for your business use case will have reduce CPU time.
