Hello Guys, I started testing serverless framework today and it is awesome, but i’m having a problem with AWS that I’d like to know if anyone is also experiencing. After creating the basic project with hello world function I attached the http event to use API Gateway and for my surprise the response time is taking around ~550ms I know there would be some latency since I’m in São Paulo making requests to us-east-1, but this is just way above my expectations So, is just me or there are other people facing this problem? Is there any recommendations to improve performance on API Gateway? ---

@renanosf what is your Lambda execution time? I assume it is very quick for a hello world, but it is worth asking. ---

Just 2ms testing from the lambda console ---

We use runscope to monitor our endpoints. We see similar latency from the Brazil location. I’m not sure about methods of improving this other than developing a multi-region architecture. Would like to see if others have solutions. ---

Well, I hope aws to launch api gateway and lambda in São Paulo region anytime soon. Although I’m not sure about that after all that time without it. ---

Just to be perfectly clear, you did try doing multiple requests? Because first request is supposed to be slower but subsequent requests are faster. I get similar latency from EU to US with my first request, but it’s good afterwards. ---

I did a test with 1000 requests and the average time was 551ms. Now the weird part of the test is that once in a while the request returns in ~200ms as I was previously expecting ---

I have similar issues from Sydney to us-east-1 and us-west-2. For example: I have a Rails app hosted in us-west-2 that responds in about 450ms but the Lambda function via the API GW is taking 750ms despite the Lambda function itself running in less than 50ms. us-east-1 was even worse at 950ms and you needed to double those times from a user perspective if it triggers a CORS pre-flight check. In the end I’ve decided to no worry about it. I can find ways to keep the response times within acceptable limits and being able to easily scale wins. ---

Is API gateway always putting 200-300ms of latency in front of lambda requests: > **[AWS latency comparison: API Gateway vs Lambda vs Bare EC2](https://www.prerender.cloud/lambda-latency)** > > AWS Lambda, API Gateway and EC2 latency compared over a 24 hour period within the us-east-1 region It’s an ongoing problem: [https://forums.aws.amazon.com/thread.jspa?threadID=225458](https://forums.aws.amazon.com/thread.jspa?threadID=225458) Has anyone found a way around it? It seems Lambda + API Gateway only avoids this latency if your app is already so large that you’re doing 100 requests per second (per function).
