** Average upload time of 10MB in seconds from EC2 server locations to S3 locations.
Combined upload times by EC2 regions
- Australia is the slowest uploader to the rest of the world, or simply down and under. Unless your only focus is Australia, you wouldn’t want to place your first EC2 instance there. On the bright side, new infrastructure developments from Singapore to Australia had a dramatic impact compared to last year, a stunning 36x faster - from more than 3 minutes (!) to 5 seconds.
- California is the best place to upload from. Second year straight, the fastest average upload time was recorded in California. If you’re considering in which region to place your next EC2 instance, it’s the best bet even if you’re not necessarily uploading to US servers.
- It’s still kind of tough to upload to Brazil’s S3. The fastest upload time to Brazil’s S3, excluding it’s own EC2, was over 5 seconds. An improvement from last year (8.83s) but still trailing behind. It’s also the weakest link for Singapore, Japan and Australia. A new fiber optic cable connecting Brazil directly with Europe is planned to arrive, so the future looks brighter.
- If we’re excluding uploads to Brazil’s S3, Japan gets 2nd best upload times after California. Yes, even better than Oregon and Virginia. In fact, for a global reach, instances in Japan and Ireland provide a pretty good worldwide coverage, averaging a 2.77s upload time.
- Australia beats any other option in same location uploads. Transferring data from EC2 to S3 in the same region is 1.3x to 8x faster than any other location. In this category, Australia takes the lead from Oregon, which was the fastest last year, and is now last (See the diagonal on the results table).
- California’s S3 is also the best to upload to from other EC2 locations. The average upload time to California was 5.39s, with Singapore as the runner up with a 5.69s average. In addition, compared to last year’s results, uploading to California improved by a whopping 58.78%. Take uploads to Brazil for example, from 28sec in the 2013 benchmark to 6sec today.
- It’s faster to upload from Virginia to Singapore than from Oregon to Virginia. In fact, if we’re looking only at the slowest upload times in each region, Virginia is the fastest among them and even outperforms California. Putting up 2 servers at these locations and expecting them to communicate fast is not such a good idea.
- The direct upload path from one point to another might not be the fastest one. Uploads from Australia to Brazil takes 61.24s. However, if you take the same path through Singapore, it will take you 22.56s, almost 3x faster. I wonder what Dijkstra would say.
- Amazon Web Services are getting faster. Overall, we see an average 32% improvement in individual upload speeds compared to our results from last year. 54 of the 64 average upload times had become faster. So even if you're using one of the slower regions, cheer up - it could have been worse.
