I think it's fairly safe to assume it's something that can be fixed. That kind of latency takes a couple minutes to pinpoint (and hopefully fix) if you have access to the server/software
Out of curiosity, how would you approach this issue? Would you look at the network stack configuration? Would you strace particular services?
Well spending about 2 minutes debugging it on my end (not that I can do much without getting on the servers), it looks to *me* like it's something above the application. Load balancers (BIG-IP), Varnish or *maybe* web server. So in this case, I'd first just yank Varnish out of the loop and see what happens (my gut feeling is that is where the problem is).

Shawn already answered, but it really depends on where the delay is coming from. Once you can target the actual delay (php, webserver(s), MySQL, etc) you can start resolving it.
It's how to pinpoint the target of the actual delay that I am interested in.
I remember a higher than usual time to first byte delay in on of my server installations once, and it turned out that it was caused by too many PHP fastcgi processes, which the CPU couldn't handle (nowadays I am using php-fpm which is easier to fine-tune). Back then I discovered it through trial and error; of course I'd have preferred a more systematic approach.
There really isn't a magical formula to pinpoint problems... otherwise servers would just find the problems themselves and fix themselves.
Just need to go digging and look around at things for anything out of the ordinary. Monitoring everything you can proactively is always a good thing. A perfect example... ~6am this morning one of my web servers spiked on it's system load (bottom chart)... and if you look closely at the top chart, you'll also notice at the exact same time, Apache on that server stopped serving requests for a couple minutes.
Ultimately what happened was the load balancers saw the server struggling with something and stopped sending requests to it until it worked itself out. Not exactly sure what the load was from, but it was brief and everything "self healed" so it never was an issue. But the point is that the more stuff you can monitor and get nice charts to compare to historical trends, the better.
So in your case, monitoring things like PHP memory usage, number of processes, etc, etc. would be a good thing.
That is not my problem either. You are making a commercial product, so no one has to report the bags. It's you job to test software are fixed them. I will stay and judge from the far. Then I'll make my decision is your product worth paying money?
I kinda give up paying money for a product just to work as an unpaid beta-tester for while. You want my help -you gonna pay me for that.
Overall Appearance/GUI
Updated, yes, and cleaner yes, but perhaps too much of a change. it looks and feels like a simple, dumbed-down version of a forum, and there are really no visible design...
This may be a dumb question but I have a website that already has a unique homepage that was coded from the ground up. I wanted to add vb5 in a /forum sub directory. Is VB5 meant to run within a sub folder...
Just a thought, but from someone who has been running a company since I was 18 years old my gut feeling here is not good. I think the only way to save yourselves is to refund those that purchased VB5,...
I was able to write a simple CMS in php with a mysql backend with more features in one day. You should just delete VB5 and close your company. Your software has become an embarrassment to forum administrators...
