I have a droplet that I’ve been using for years to develop on, using the Cloud9 browser based IDE.
Ubuntu 16.04.6; droplet: Basic / 2 GB / 2 vCPUs
Recently whenever I open the IDE my CPU and ram shoot all the way up and I can’t do anything.
“kswapd0” is always using a lot of CPU

Hello @skeddtemp
Researching on this
kswapd0
, manages virtual memory and may be having issues due to moving processes to SWAP too frequently, causing CPU spikes and decreased system performance.I recommend tweaking your SWAP Settings if you haven’t done this yet. This should improve the performance of the droplet.
