there have been some improvements! when i changed my avi, i noticed that it updated in the header on the forums right then. also, over the past few months when i'd choose to display my gold emblem, it would take twelve to twenty-four hours for it to show in the forums. last night it was instant. my unread messages sync sooner now as well.
ETA: seems i must've checked during the sweet spot earlier. did a test today and marked a message unread. it's been over two hours and my mail on the forum header has yet to sync.
Due to the desktop site serving over 15 million monthly pageviews, to 1.3 million monthly users, the only option on a shoestring budget, is to heavily cache the site. Hence the delays.
The alternatives are we remove a whole bunch of features and make it a static site like *cough* inferior sites out there, add a mobile version which (hopefully) supplements our income and allows for technical improvements down the track, or we close the site.
We're doing everything we can to improve the site (s) across the board.
I think some people are forgetting that until a few months ago, we've only had one person managing the servers, for 12 years. Gav works as a full-time programmer elsewhere, and has a busy life outside of work. He only has a few hours a week available to work on the site.
Thank you for your understanding.
