I am currently with IPB 3.3 and since I've been having several problems I would like to transfer my board to XenForo.
According to the IPB people, the problem is the huge database we have (20 GB) and some huge topics created in the forum, for example, one topic has 89,991 replies and 16,757,907 views, another 29,233 replies and 345,511 views, and so on.
My community currently has over 400,000 registered users and over 17,000,000 posts. The average of online users per day is 1000 with peaks between 1500 to 2000. I mentioned this because I have seen many forums with larger numbers than mine so I should be fine with this but my main concern is the issue with my topics with a big number of replies. Is this still a big issue if I transfer my board to XenForo?
Big topics really are a problem with Invision. Once you hit over 50k replies, you're on you own. Bug in practise, even just more than 10k replies in one topic bring those slow queries and kill the entire board with it.
We pushed several tickets and waited over several big version jumps, from 3.1 to 3.4, and nothing about this performance issues has ever happen. In fact, they just put even more features an load into topic views, and appears like they don't really get or care about this problem.
Their response and solution was to tell us to delete posts inside those big topics (their moderation tools are not very well polished to do something like that in batch). Or even to delete those threads and start over.
There one in particular that it's VERY important but in terms of newcomers. It drive traffic as hell from google to us.
Can we expect problems like this on xenforo? i mean with really big topics, with more than 50k replies on it?.
Also, how long does the transfer from IPB to XenForo take?
We already have a big tweaked bunch of servers, now on AWS.
We use nginx. Have memcached installed. And a big etc. of tweaks and enhancements over the years.
Thank you in advance.
