@pawan-patil You are able to modify the source code and use it on your own site. You are only limited if you are intending to redistribute the code. If you intend to, then you must also open-source your changed code.
If in doubt, you'll want to contact a lawyer to review the GPLv3 license that comes with NodeBB.
@meetdilip Yours definitely seems slower than it should be. I just tried and got 5.15 seconds, but each of your requests takes slightly longer. you're on digital ocean correct? Which server did you go for? Amsterdam 2 or New York?
My homepage is loading in 3.18 seconds, but each request is completing faster for me.
Getting socket.io for example took 900ms on your site, but only 163ms on mine.
Thanks @a_5mith . Could please tell me what I should do. I use default lavender theme with just colours changed. Is that the plugins that is slowing down forum ?
