The company I work for uses a virtual server for computers in the office and workshop to connect to and do work on. At one time, there are approximately 25 terminals connected to this server.
Last week, we had a brownout that lasted for about 30 seconds; after the brownout, we noticed the server was running slow. After further inspection, we found that instances of Chrome for 2-3 users at a time were each hogging up as much as 30% of the entire server's resources. This kind of usage happens even when they have <5 tabs open on common sites.
To try to alleviate the problem, I have disabled hardware acceleration and no longer allow Chrome to run apps in the background after it is closed for everyone. According to scans, no malware seems to be present either. However, the problem still persists.
What could be causing this to happen?
For reference, we have a dual-socket Xeon E5-2620 v3 @ 2.4 GHz, each with 14 virtual processors.
