Unfortunately, the results for Google Translated Search are generated in more than a second and sometimes you have to wait 5 seconds to get the results.
It's strange to see Google releasing a slow feature on the main site. O'Reilly Radar shared some interesting results from Google's experiments:
"One experiment increased the number of search results per page from 10 to 30, with a corresponding increase in page load times from 400 milliseconds to 900 milliseconds. This resulted in a 25% drop-off in first result page searches. Adding the checkout icon (a shopping cart) to search results made the page 2% slower with a corresponding 2% drop in searches/user."
