There are a few different places to get drivers (Fedora site, RHEL subscription, build yourself, etc). From the graphs, it looks like the speed isn't too bad at times. But it's hard to tell with the information you've given about your particular config. I mean 50MB/s isn't bad for a single rotating disk on raw storage. But we don't know what kind of setup you have since you didn't tell us. > > All that can be tried, but failed to increase the speed. And there I > have a database running. All? You should try being specific about what you've tried. How you are running the guest. The underlying hardware. Command line options. Too much detail is better than none (which is about what you've given us). > > Screenshots test speed drives > > http://itmages.ru/image/view/1471772/feec35c3 > http://itmages.ru/image/view/1471774/2b0baeae > http://itmages.ru/image/view/1471785/9fffb8f5 > > Thanks in advance.
