High CPU usage with node

[erickhun]

Hi aws team!

I'm running the KCL client for reading 10 shards.
It seems like the for some simple log operations, each process take up to 45% cpu usage on a m3.xlarge. I was wondering if that was normal, or if I'm missing anything ?

Thank you for your insights

I'm also seeing crazy high cpu usage on a c3.large that's not doing anything too crazy. What confuses me is that it's always at ~100% even if I shut it down for a few hours and it needs to catch up to the latest records from kinesis. I know this post is from 2 years ago but did you have any luck figuring out what's going on?
