AWS S3 Performance for AU Business: Latency, Throughput & Cost Optimisation

24 Jun, 2025 |

In today's fast-paced Australian business landscape, data isn't just an asset; it's the lifeblood of innovation, efficiency, and competitive advantage. From e-commerce platforms handling millions of transactions to media companies streaming vast libraries, or FinTech firms processing mountains of financial data, the ability to store, access, and process information rapidly and cost-effectively is paramount.

Amazon Web Services (AWS) S3 (Simple Storage Service) has become the de-facto standard for cloud object storage, offering unparalleled scalability and durability. But simply "using S3" isn't enough. For Australian businesses managing high-volume data workloads, the true differentiator lies in optimising S3 integration performance. This isn't just about technical jargon; it's about directly impacting your bottom line, user experience, and ability to scale.

This article, brought to you by C9 – Australia's leading custom software, apps, integration, and database developer – will cut through the noise. We'll delve into the critical aspects of S3 performance: latency, throughput, and cost. More importantly, we'll share insights derived from actual benchmarking, providing you with actionable intelligence to ensure your AWS S3 integrations are not just functional, but truly optimised for your business success.


 

The Performance Triad: Latency, Throughput, and Your Bottom Line

Before we dive into our findings, let's clarify why these three metrics are crucial for your business:

  • Latency: This is the time it takes for a request to travel from your application to S3 and back. In simple terms, it's the "lag." For real-time applications, interactive dashboards, or critical business processes, high latency translates directly to frustrated users, delayed insights, and potentially lost revenue. Imagine your customers experiencing slow load times on your e-commerce site – they won't stick around.

  • Throughput: This measures the amount of data transferred over a given period (e.g., MB/second or GB/second). High throughput is essential for applications that deal with large files or frequent data transfers, such as video processing, big data analytics, or large-scale backups. Insufficient throughput means your data pipelines crawl, impacting productivity and time-to-market.
  • Cost Optimisation: While S3 is often perceived as cheap, unoptimised usage can lead to ballooning bills. Every request, every byte transferred, and every storage class choice has a cost implication. Understanding how to align your data access patterns with the right S3 configurations is key to maintaining profitability.

For Australian businesses, particularly those operating with significant data volumes, these aren't merely technical considerations – they are strategic business decisions.


 

Our Benchmarking Approach: Real-World Scenarios, Tangible Results

AWS S3 Benchmarking Approach Real-World Scenarios Tangible Results

At C9, we don't just talk about performance; we measure it. Our team of expert developers and cloud architects regularly perform rigorous benchmarking to understand the nuances of AWS S3 performance under various conditions. For this deep dive, we focused on common high-volume data workload scenarios relevant to Australian enterprises.

Our Test Environment:

  • Region: Sydney (ap-southeast-2) – Critical for Australian businesses to minimise network latency.
  • Data Types: Varied, including small objects (1KB, 10KB for metadata/logs), medium objects (1MB, 10MB for documents/images), and large objects (100MB, 1GB for video/large datasets).
  • Operations: GET (reads), PUT (writes), LIST (directory listings).
  • Tools: AWS CLI, custom Python scripts using boto3, and open-source benchmarking tools like s3-benchmark for specific scenarios.
  • Workload Simulation: Single-threaded operations for baseline, and multi-threaded/concurrent operations to simulate high-volume application traffic.

 

Actual Test Results & Comparisons: Unpacking the Numbers

Here's a glimpse into some of our key findings and what they mean for your business:

 

1. Latency: The Millisecond Advantage

Operation Type Object Size Single-Threaded Latency (ms) Concurrent (50 threads) Latency (ms) Impact on Business
GET 1 KB ~25-35 ms ~40-60 ms For web applications serving small assets or real-time analytics, every millisecond counts. High concurrency slightly increases individual request latency but dramatically boosts overall request rate. Faster page loads, snappier applications.
GET 1 MB ~30-45 ms ~50-70 ms Retrieving documents, small images, or frequently accessed files. Still low, but demonstrates the overhead of network transfer.
PUT 1 KB ~30-40 ms ~50-75 ms Storing logs, session data, or small transaction records. Efficient for high-frequency write operations, crucial for event-driven architectures.
PUT 1 MB ~40-60 ms ~60-90 ms Uploading user-generated content or small files.

 

Insight: While individual latencies for small objects are low, the cumulative effect in high-volume, concurrent environments can lead to noticeable slowdowns. Strategic use of CloudFront CDN for frequently accessed content significantly reduces latency for end-users, especially those geographically distant from the Sydney region, by caching data at edge locations across Australia and globally. Our tests with CloudFront showed latency reductions of up to 70% for cached objects on repeated access.

 

2. Throughput: Powering Your Data Pipelines

Operation Type Object Size Single-Threaded Throughput (MB/s) Multipart Upload (8-16MB parts, 50 threads) Throughput (MB/s) Benefit
GET 1 GB ~80-120 MB/s ~500-800 MB/s Essential for analytics, machine learning training data, or large file downloads. Multipart allows parallel downloads, dramatically increasing the speed at which large datasets can be consumed. This translates to faster data processing and quicker insights for your business.
PUT 1 GB ~70-110 MB/s ~450-750 MB/s Critical for large-scale data ingestion, backups, or media uploads. The ability to break files into parts and upload concurrently makes a massive difference for high-volume data sources. This ensures your data lands in S3 rapidly and reliably.

 

Key Throughput Enhancers We Benchmarked:

  • Multipart Uploads: For objects larger than 100MB, multipart uploads are a game-changer. Our tests consistently showed 4-7x improvement in throughput for large objects compared to single-part uploads. This is crucial for businesses dealing with media, large sensor data, or extensive archives.
  • S3 Transfer Acceleration: For users uploading data from geographically distant locations (e.g., a team in Perth uploading to Sydney), S3 Transfer Acceleration routes data through CloudFront edge locations, significantly improving upload speeds. In our tests from a remote location, we saw upload speed increases of up to 30-50% depending on network conditions and distance.
  • Prefix Optimisation: AWS S3 can handle thousands of requests per second per prefix. For very high request rates, distributing objects across multiple prefixes (folder1/object1, folder2/object1) can prevent hot spots and allow for linear scaling of request rates. This is a subtle but powerful optimisation for extreme workloads.

 

3. Cost Optimisation: Smarter Spending, Greater Value

Optimising S3 performance isn't just about speed; it's about smart spending. Our benchmarking also focused on the cost implications of different S3 strategies.

  • Storage Class Selection:

    • S3 Standard: Our baseline, good for frequently accessed data (e.g., active websites, frequently used applications).
    • S3 Intelligent-Tiering: This class automatically moves data between access tiers based on usage patterns. Our simulations showed that for data with unpredictable access patterns (e.g., evolving analytics datasets), Intelligent-Tiering could lead to savings of 20-40% over S3 Standard, as it automatically shifts less-accessed data to cheaper tiers without performance impact.
    • S3 Infrequent Access (S3 IA) / S3 One Zone IA: For data accessed less frequently but still requiring rapid retrieval (e.g., backups, archives not needing immediate access), these tiers offer up to 70% cost reduction compared to S3 Standard. However, remember the slightly higher retrieval costs.
    • S3 Glacier / S3 Glacier Deep Archive: For long-term archiving with infrequent access, these offer the lowest storage costs, with retrieval times ranging from minutes to hours/days. While not for performance-sensitive integrations, they are critical for significant cost savings on historical data or compliance archives.
  • Lifecycle Policies: Implementing S3 Lifecycle Policies to automatically transition objects between storage classes (e.g., from Standard to IA after 30 days, then to Glacier after 90 days) can lead to substantial long-term savings without manual intervention. Our analysis indicates that a well-defined lifecycle policy can cut storage costs for older, less-accessed data by up to 80%.

  • Data Transfer Out (Egress) Costs: This is often the hidden cost. Transferring data out of AWS to the internet can be expensive. Designing your architecture to minimise egress (e.g., processing data within AWS, using CloudFront) is crucial. Our testing showed that leveraging CloudFront for content delivery can reduce egress costs by leveraging caching and reducing direct S3 access, effectively transforming expensive S3 egress into more affordable CDN data transfer, especially for globally distributed users.
