Sorry about the really really slow community, it's something we are aware of since the 6th December and has (as well as a few other issues) been raised with our platform provider (now also escalated). I am experiencing the same speeds you are (which is slow to snails pace) so were all in this together
We did pop up a Service Issue thread last week regarding this & other issues which you can view here: https://community.giffgaff.com/t5/Service-Updates/Ongoing-Community-Platform-Issues-6th-December-201...
We are on the case and as soon as we know more we will share this with you.
Once again we apologise for this & appreciate your patience.
