You are mixing up several issues into one.
The pages an topics with huge amount of syntax highlighting are luggish due to the amount of html tags the codebox generates (doesn't help that there are additional link tags inside the span tags).
This puts a large load on the browser- Google Chrome generally seems to be better at dealing with this amount of tags.
there isn't a lot we can do here - we took the syntax highlighting feature from somewhere else and will have a hard time modifying it.
I honestly don't see the need to switch to another codebox versions - the current one works just not for massive files.
The site is neither intended for the storage or the sharing of massive files in the posts body.
This problem is actually a serious problem since an attacker could purposefully post a topic with so much code that the visitors PCs will crash.
We might have to lower the amount of characters you can post inside code boxes.
Personally I don't think Attatchments are a solution - to me they combine the worst of all the worst attributes.
If you want to host and share your code there are websites specifically made for that - you should use them to share code here.
I also do agree that sharing code is an issue in the forums. Code boxes are not an option - they are made for single files while even basic scripts usually are multiple files.
One soltuon that we discussed in the staff forums would be to add another software to this websites that is specifically made for storing and sharing software and have the forum software interact with it.
The second issue is network related. Jusging from what tank said too many people try to automate the website.
So now we try to catch the bots and limit their access. The rules are still in the making so they might catch legit users.
Afaics there are no other issues. You of course complain about more, but generally most of the stuff you say about forum usage programming etc. has as much relevance to me as the ramblings of a flat earther about the earths shape and geography.
Im only listening and responding to you out of a sense of responsibility to my duty as Administrator here in the forums.
That last sense of duty is slowly declining as you keep complaining about issues when abusing the forum software for something it isn't made for with a 4 year old discontinued browser.
Have a nice day and keep up the good work
