title: Google Sheet IMPORTHTML VERY Slow?
body: <p>I have a spreadsheet that acquires some table data using the IMPORTHTML function, and for the first two days I was using it (refreshing twice daily) things were going fine.  As of this morning, it is absolutely crawling.  Went from taking ~15 seconds to load 30 rows to taking ~10 minutes.  Can somebody lend aid on this?</p>
  
  <p>Example formula:</p>
  
  <pre><code>=IMPORTHTML(
    "http://www.muthead.com/16/players/prices/1508-markus-wheaton/playstation-4","table",2
   )
  </code></pre>
  
  <p>As mentioned, the first couple of days it was able to refresh and process a list of 30 without any pauses.  Now I get the 'Executing script' message for about ten minutes before it begins to do anything, and I haven't touched the source code since origin.  I'm not sure what contributes to the performance of the IMPORTHTML statement...</p>
