the speed of open web site is slow in our local(asia), is cause by web hosting company or Nopcommence itself?
Please host your site somewhere other than at LA data centers. LA (or around) data centers have some bandwidth issues against Asia.
the famous hosting company discountasp.net (its data centre provider is based in LA or around) has very slow connection from Asia while ServerIntellectual (Denver based) provides astonishing speedy connection to Asian web shoppers. Nothing to do with great product NopCommerce.
I have tested around more than 50 web hosting companies...and most are based in LA or around. All of them have very slow connection from Asia. Web hosting companies blame user end or under sea cables or data center providers..Data center providers totally ignore any network speed issues as saying their system don't alert any problem so far.
