'Are app engine instances CPUs throttled after a while?
I'm using a App Engine task handler, to process a workload (import files to database). Looking at my Cloud SQL monitoring, I see that after some minutes, the write rate declines (see picture), and my task runs much slower. Does Google throttle the Instance's CPU or might there be other reasons?
Solution 1:[1]
Most services including Cloud SQL provide an IOPS quota which is based upon disk size and other factors.
Your screenshot indicates that you have exceeded that READ quota for Cloud SQL. The result is throttling of disk I/O.
When you created the Cloud SQL instance, you selected a very small storage disk. I recommend resizing that disk larger so that normal operations do not exceed the disk IOPS quota for both read and write.
