100% Processor utilization

[myriad]

No matter my CPU count, it's 100% with a relatively high load average of 9-13 I've given 2, 4, 6 Processors, 4GB RAM. with a hybrid drive system of 10k, SSD, and 7200 hosted in VM 5.5 This is a fresh installation of NLS 2015r1.4. I've got about 114 Hosts attached now, and as DNS propagates, I'd imagine about 200 - 250 Hosts will attach.
Any Ideas?

What is using all of the processing power?

Code: Select all

ps aux

With that many hosts being added to NLS, I highly recommend upgrading the amount of RAM you have up to a maximum of 48GB if possible. I also recommend using a cluster of three or more instances of NLS, as processing performance starts to increase at clusters sized 3 or more.

There's what I get. It has actually settled down considerably since I last posted.

I recommend upping the amount of RAM in the box to see if that has any impact on CPU performance. I'm glad to hear that it's settled down considerably - everything looks normal to me.

Could you show me a screenshot of your 'Instance Status' screen please?
