How can I make my RDS faster?

DB instance RAM recommendations An Amazon RDS performance best practice is to allocate enough RAM so that your working set resides almost completely in memory. The working set is the data and indexes that are frequently in use on your instance. The more you use the DB instance, the more the working set will grow.

Can RDS scale down?

You can scale your RDS configuration up or down to meet the increasing demands of your applications. RDS manages the heavy lifting in scaling your database and allows you to focus more on your applications.

How can I determine how many IOPS I need for my AWS RDS?

With EBS volumes you can’t just increase the number of IOPS, you’d have to scale up the size of the volume as well 1. You can always just create a new volume and copy your data over. There will be some downtime but if you’re data isn’t huge it shouldn’t be much as it’d be a raw copy.

How many IOPS does one hard disk use?

This means that the transfer rate is 75MB/s and consumes 10 IOPS, which is well within the capabilities of a single hard disk. The second workload requires reading ten thousand 750KB files, the same amount of data, 7.5GB, but it consumes 10,000 IOPS.

How can I determine how many IOPS I need for my application?

I use iostat to determine the amount of IOPS my application is performing. iostat reports this as tps. KB/t helps you determine if the amount of the transfer is less than the chunk size, 256 KiB. I run iostat with a one second wait time, i.e. iostat -w 1.

What are IOPS and what should you care?

For example, if all vendors state they would report IOPS from tests using 4k block sizes and 50% random read/write mix, the resulting number would have little meaning to a data center whose workloads were generating 32k blocks with an 80% read to write ratio.
