Optimise async request / code [For Beginners]

[demetera]

Dears,

is there any way to optimise this little piece of async code to make faster 
response and shorter code maybe? URLs and search string being provided only for 
the researching purpose.
    
    
    import std/[httpclient, asyncdispatch, strutils]
    
    const urls = @[
      "https://www.google.com";,
      "https://www.yahoo.com";,
      ]
    
    proc getContent(url: string): Future[void] {.async.} =
      let client = newAsyncHttpClient()
      let content = await client.getContent(url)
      echo url & " " & $content.contains("tag")
    
    var futures : seq[Future[void]]
    
    for url in urls:
      futures.add(getContent(url))
    
    for future in futures:
      waitFor future
    
    
    Run

I'm mostly curious about for loops.

Thanks
