I just used too many mikrotik devices in few places, that I seriously hate to reconsider this decision based on how they handle their bugs. And what is customer to do, if there is no visibility into their actual bug fixing processes? Customer looks at what it can actually see - forum that behaves like nasty turd thrown onto wall by them and slowly slipping downwards... People who make fun of that, get their message deleted. But turd remains, keeps sliding down slowly. And then these kind of excuses like we had here.
Had too many way harder performance issues in my development time and had to manage too many badly behaving web apps in my sysadmin time to have any damn tolerance for actual company who does such a crappy job on their client-facing forum. And no, not just does shitty job, actually presents that as an excuse if client asks, why this is so slow lately... Seriously - fire this crappy-excuse-producing thing who sits on your sysadmin desk. In my own business I would additionallyt have one stern talking session with others who allow excuses like this to be presented to customers. Just leaves whole company looking incompetent, to say the least.
