Images missing alt elements has nothing to do with speed.

I also see delays - the main server is then reacted first request after more than 8 seconds

In 4.1 Preview site for this function Activity I expressed doubt that there will be too many http requests to the server and work slowly.

Any error in the template builds microseconds delay. In too many http requests amount of time delay increases. If my request Activity waiting processing 50 other - that at least 50 microseconds completely unnecessary.:smile:

What are you talking about? This is about server response time. It takes 7 seconds just for the server to tell you which external resources to load. In those 7 seconds it just makes one request, which it made at second 0.

The problem is clearly about inefficient PHP and/or MySQL execution.

IMO the HTTP requests should not be a problem. I think the SQL queries and/or PHP runtime of IPS 4.1 are grossly inefficient. :(

Can flog SQL servers so hard though so I highly doubt it's related to SQL (I am a systems engineer for an ISP in Australia and we use MySQL (lol))

Take out your .htaccess - see if there is a difference in load time.

Invision seems to develop in the wrong way. First they build a function and then they want to make it fast(er).

:(

No, they do it the right way.

There are many situations where developers are pushed with time and have to get things out on a deadline, they can then go back later and make improvements.

Definitely a normal thing

The hype for PHP 7 is real

I repeat what I said a post before: Hopefully Invision can do it. At the moment it is unusable and a bad walking advertisement.

It was just installed here to test everything on a live big board to find and address possible performance problems. The problems can then be fixed and tested again within the beta cycles before the final release. So its running its normal development course. No need to claim IPS is doing something wrong.

As was posted above, performance improvements are the last thing we do as that is the proper way to code projects. We will be doing performance in the next week.

Sorry, yesterday you said you will be addressing performance this week -- was that pushed back or just a typo? :)

It loads pretty quickly for me. I do not see any significant speed issue at the moment.

I believe an update was just pushed through that addressed the performance issues with notifications, it's back to normal for me now after the recent brief maintenance break.
