Hello everyone.

 

Currently testing the system and while there is up to 180 requests per second, system performs as designed without any problems, but while requests jump over ~200, response time goes sky-high.

 

Is there something that could be tuned to optimize performance or where to start looking for problems?

Darko:

 

Need a little more information to even begin to answer this.

What type of HCP?

What application is doing the requests?

GETs? PUTs? Both?

Is the cluster doing anything else (servicing other apps/requests)?

Have you tried running Content Monitor (instead of Grafana) to better understand what HCP is doing?

Hello Jonathan.

Setup is HCP VM with 2 nodes. Currently nothing else is running on them, tests only.

People are using Jmeter tool for requests, PUT generates random files - %hostname%/rest/%fixed_folder_per_client/%random_folder_each_request%/%randomfile[10k, 100k,1M,5M]%

Both, but GET is used in ~20% of time.

Only Grafana is used for monitoring.
