Your Teacher Told You, Slow and Steady wins the race
But… You Took It in a wrong way. You applied that principle for your website too and now you think that your slow website will win the race among your competitors and will help you get more leads and sales.
Come on! Sorry You are wrong here.
Your website should be fast enough to offer a good user experience. Even Google has officially declared just some time back that speed is an important ranking factor.
Want to check speed of your site ??? You can use tools like GTMetrix, Pingdom and Google page speed Insights.
