A bit of searching shows that others are complaining about the same problem. That does look like a substantial hit. What happens if you try the workload on a new VM? Roll the dice until you get lucky maybe? This server is not so bad but it really shows the change in performance. The one that keeled over on me was on a small instance and I had to move it to a large instance. I did a bunch of database clean and hopefully that will be enough to be able to put it back on a small instance. Otherwise my costs at AWS till jump significantly.
am also seeing major perfomance hits at other providers, costs are going to be a lot higher for some projects ---
Maybe time to renegotiate pricing? Dee
"Big update here! Looks like AWS/EC2 just deployed an updated #Spectre patch (perhaps Retpoline-ish), addressing high IO HVM instance performance issues! Big credit to Amazon for addressing performance needs & concerns so quickly and diligently. Thank you. cc @_msw_" https://twitter.com/chanian/status/951891326366175232 On Fri, Jan 12, 2018 at 7:45 AM o1bigtenor via talk <talk@gtalug.org> wrote:
