I apologize if you came to this site and it was slow.
I just upgraded the VM that runs this site to address the problem. I am hopeful there will be fewer problems now.
It appears that the old VM was memory-bound or near-memory-bound a lot of the time. This was likely leading to the CPU problems because of paging.
Now the VM has room to breathe on the memory side and I believe that will resolve the problem. I have no proof that memory was the actual problem, only a correlation between slow times, higher memory usage, and CPU spikes. Time will tell if this resolves the issue.
In the meantime, paying a few more bucks to see if things get better seemed like the right thing to do.
I'm in the midst of reading Ubik by Phillip K. Dick.
Here is an interesting theme from the book: people pay for a great many things as a service, instead of owning the use of those things outright. Many of the instances in the book are a bit silly for us in 2016 - a coin operated door to an apartment, for instance. But we have the benefit of an additional 45 years of history and science that PKD did not have in 1969, when Ubik was published.
Today there are a lot of things that we pay for in an ongoing way (albeit not with coins) - phones, books, music, computing power, automobiles, genealogy information, etc.
Phillip K. Dick was able to imagine a version of our electronic, service-based, cloud technology world well before any of it existed.
That he got some of the implementation details wrong is hardly surprising, given when he was writing.
A lot of old science fiction gets those sort of details wrong. It can be hard to look past those limitations sometimes - it's easy to focus on coin-operated doors or old special-effects technologies. But if you do, really good sci-fi gets a lot of things right. Heck, sometimes even bad sci-fi gets a few things right.
It's a healthy exercise in ignoring details when the details aren't the thing that matters - what mattered then (as now) was imagination and storytelling. PKD got those things very right a lot of the time.
Also, if you are ever in Ft. Morgan, CO, USA, you can visit Phillip K. Dick's grave. It is located in Riverside Cemetery. The people there are happy to help show you where his grave is located. He is buried with his twin sister who died when she was an infant.
