Forum getting slower frequently now?

I’m curious to know if the webmasters are aware that this forum is getting slower to load more frequently over the last week or so? I’ve exhausted all the usual user-end options (I’m a pc fixer so quite aware that at my end it may have been my pc needing a clear-out) and comparing my frequently visited websites – this one stands out as very obvious. Page loading when first visiting each day is a nightmare with slow / partial loading at first. Once I start using one forum section and start reading posts – the forum gets really ‘clunky’. I’m on a 100mb broadband so this really should not be happening?
I suspect the server is getting overloaded at busy times (there is no obvious really quiet time from what I can tell)….
