I/O Performance

Cloud Mercato's tested the I/O performance of this instance using a 100GB General Purpose SSD. Below are the results:

Read Write
Max 3098 3098
Average 3098 3097
Deviation 0 0.6
Min 3098 3096

I/O rate testing is conducted with local and block storages attached to the instance. Cloud Mercato uses the well-known open-source tool FIO. To express IOPS the following parametersare used: 4K block, random access, no filesystem (except for write access with root volume and avoidance of cache and buffer.

The t3 family is a burstable instance type. If you have an application that needs to run with some basic CPU and memory usage, you can choose t3. It also works well if you have an application that gets used sometimes but not others.

Amazon T3a instances share similar features with T3 instances, except that they run on AMD EPYC 7000 series processors, clocked at 2.5 GHz (all core Turbo).

I think the discrepancies can be attributed to the choice of the t-style instances. They are generally over committed.

Aren\'t \'t\' instances burst instances? They need to be under constant load for a long time before their burst credits for CPU, memory, network and EBS run out, after which they fall back on their baseline performance.

To me, this implies they used a single ec2 instance of each size. However, ec2 instance p99s or so can be impacted by \"noisy neighbors\", especially on the burstable types which are intentionally oversubscribed.

Thank you for this article. We have T instances for EC2 and RDS and we are expecting some very strange performance behavior. Do you have plan to test RDS?

t3a instances run on AMD EPYC CPUs, depending on your workload (threads, spikes, etc.), you will probably have similar performance if the right pieces match.

In general, it seems that the t3 instances running Intel CPUs are usually faster. You can also get a 10% discount on your EC2 computing bill:

T3a instances have AMD EPYC 7000 series processors with an all-core turbo CPU clock speed of up to 2.5 GHz. T3a instances offer an additional 10% cost savings over T3 instances.

We cannot possibly know how these will perform for your workload. Rent both and test. Optimize according to your requirements: cost, performance, whatever.

For T3 and T3a instance types Unlimited mode is turned on by default. This is excellent, as we remove the risk of a production outage, but gain the risk of increased costs.
