A quick update on a change in the website:
I've now switched the main web-server to a new provider. But - I have not yet moved the site database over. You may find that sometimes the response a bit sluggish - this is why.
I'm in the process of migrating the database, and once that is done, I expect zapread to be "zippy".
The new web server is also much more easily scalable, and I don't expect that any future upgrades will be a problem.
Thanks everyone for your understanding!
