title: Very slow IOPS on Google Cloud SSD. Why?
body: <p>I have the following server on Google Cloud: 8vCPU, 16GB memory with 50GB SSD system disk and 1024 GB SSD for data.</p>
  
  <p>But it's very slow:</p>
  
  <pre><code>  read : io=3071.7MB, bw=4503.4KB/s, iops=1125, runt=698463msec
    write: io=1024.4MB, bw=1501.8KB/s, iops=375, runt=698463msec
  </code></pre>
  
  <p>I have only 1125iops on the 1TB SSD disk. Any idea why it is slow slow? I've got ~23.000 iops on Rackspace with similar specs...</p>
