For me it's so unresponsive that I'm at a loss for words how google put this into production. I have a modern, new computer and modern, urban internet good enough for streaming 1080p on Twitch without interruption, but I can't delete or archive an email anymore without waiting 4-6 seconds for it to complete the action.
What has your experience been like with it?
edit: Guess I'm not alone. I can only hope someone working at Google sees this post or cares. Maybe too much to hope for.
