The website uses lots of plugins but it should be run smoothly even on an average platform specifications.
But since you told us that feedback, I suggest to the devs/owners, if possible, to provide a mobile/lite version of this exchange. In this way, people that away on their desk can lightly accessed the website even they will use their resepective native browser. It can also save bandwidth for those mobile users resulting for much speed when accessing the site.
Ah okay got it. Yeah maybe mobile/lite version will be good. hope they will add it as soon as possible
