Hello all, can someone explain what's the "NetSuite System" in the APM and how to improve it ? thanks a lot.

there are a good amount of factors that could affect that column. System time normally is comprised with the time spent by system to 1. Fetch the customizations <SuiteBuilder level> linked to a given record time 2. Perform system validations 3. Saving the record into the DB 4. Retrieving back the information to be presented to the user You could improve it to a certain degree by controlling the customizations linked to the form viewed by the user or for a certain role. Also, your preferences in also affects the overall performance of the record

thanks a lot @クリスピポテト

Since you are looking at save on orders... Here's a tip: If you have a beforesubmit script that edits the item sublist in any way, the lines will need to be recalculated and that extra time will also show up as Netsuite system-time even if it is directly related to the script. In the page time details, you will notice as a rather large gap right after the beforesubmit-script and any other beforesubmit-actions. Sometimes I've added a small beforesubmit-script that only logs after an existing one just to see that gap.

thanks @Watz good to know that trick.
