Of course they are using proxies, load balancers, caching mechanisms in 
the code and other methods to lower the workload, but actually this is 
not the point.

The point is, that we have been introducing stuff that significantly 
slows down the whole system. And this can't be fixed by telling people: 
Yes, we are below 50% of the performance of our LTS version, but that 
doesn't hurt as much, since you should use a proxy anyway.

I will do some profiling on the introduction package or the government 
package to find out where we lost most of the time, so maybe we can get 
back some of the performance for 6.1 or at least for 6.2,since this will 
be the next LTS.

Most likely candidates: Namespacing and class alias mapping, breakdown 
into (too) many small classes and methods, maybe a combination of both, 
Extbase (but that should not count for the default frontend output), 
Caching Framework, redundant method calls without properly reusing the 

I really would love to see at least 6.2 running as fast as 4.5 did.
So let's see what we can do about it.

Have a good night
