It works considerably ok when doing regular browsing. But when it gets to some interactions like PMs, posts etc - it gets very slow. Especially during 18:00 - 24:00 GMT. I suppose the DB is the weak spot, as considering the number of posts here, it is many many gigabytes in size, and any issues with indexing, memory caches, or just a slow hardware make lots of slowdowns. Would be nice to put everything on a dedicated hardware with a pack of RAID SSD drives (not big but many of them, like 8, and utilizing a hardware raid card with a backup battery and large onboard cache), should give incredible IO power that usually causes all the DB troubles.

Never had this before but I have new phone so this might be the issue (note 20 ultra)

Tuesday changes have been performed. I hope everyone sees improvements.THE FORUM IS A TERRIBLE THING TO WASTE!

Thanks guys for the offer of help and insight, but we are already two IT tech guys on that, and we have a decent understanding on why stuff are slow, trust me, it's not a simple problem at all. There's no easy out of the box solution we haven't already tried.

I don't know if that is the reasoning why Tapatalk has such issues - but as far as I've researched Tapatalk is using the vBulletin API so normally that shouldn't do a issue but I can't know for sure of course.
Page speed also pretend that some JS & CSS ressources are useless and should be removed, but those are vitals and are loaded as fast as any css file on any webserver : it's just text.
So always take PageSpeed results with a grain of salt and look at live performance. As I said in another topic : this version of Vb is badly optimized and outdated, it handle permission badly increasing loading time the more permission you have, log out and try the site in guest and you'll see how fast it is.
Originally posted by cool1o View Post1. Have you tried installing LiteSpeed for your servers? It is a really powerful extension which increases loadtimes by a whole lot.
I googled and found that it also works with vBulletin but don't quote me on that since the post on LiteSpeed was from 2011
2. Maybe it doesn't have anything to do with the webserver - what about your database?
I'd guess that the database is huge and could be a bottleneck if not powerful enough.
3. If it isn't the database and you can't or don't want to use LiteSpeed what about a CDN? That could possibly speed things up
2. Database is huge but is sitting on a more than powerful server, part of the test we did was to triple the hardware of the database server, it did not make a single difference in speed, so we know it's not a bottle neck here
3. We already have a CDN, our issue here is not related to static content.
Currently we know that the main and biggest issue is the version of Vbulletin we are running, until we can safely update (as you can imagine, it's not a simple click on the update button), we are testing parameters on the whole server to handle traffic surge better.
We also have a I/O problem sometime that we have difficulty to isolate as it's not constant or predictable and leave almost no trail behind.

To be clear : there's no hardware bottleneck here, we explored that some time ago, and going more powerful did not make a single difference in speed.
The weak link is Vbulletin, not as a software in general, but this current version.
And for the mention about Tapatalk, this is out of our control, I have the error log from Tapatalk, and there's a lot of them, but they are related to the queries they make on the database and that's their business to sort out

as mentioned all is pretty decent in terms of loading right now (at least as compared to previous days), only when you post something it takes minutes.
this from my powerful desktop computer, on my iPad Air 2 it's painfully slow (chrome)I'm in love with the shape of Roo // Sucker for 3-6-9 dials
