When i check network activity of my site in chrome developer tools i found that singalr/hubs script it taking long time to response. i have attached screenshot. is it normal or something wrong with implementation?
回答1:
This is very normal for Server Sent Events. Client opens one connection on server and they use this connection for communucation.
