--- Comment #3 from Raúl <rasasi78@gmail.com> ---
What I see here (kdelibs 4.14.0 + konqueror 4.13.3) is that konqueror keeps
being responsive in the first seconds (maybe first minute) of that web loading.
After that, when page is 80% loaded it starts eating memory and konqueror
starts being unresponsive.

I loaded that web on a separate konqueror instance, in the only tab. It took
about 1.3GB RSS. This is a system information memory report:

Summary

The process konqueror (with pid 15109) is using approximately 1.2 GB of memory.
It is using 1.2 GB privately, and a further 19.8 MB that is, or could be,
shared with other programs.
Dividing up the shared memory between all the processes sharing that memory we
get a reduced shared memory usage of 5.8 MB. Adding that to the private usage,
we get the above mentioned total memory footprint of 1.2 GB.

Library Usage

The memory usage of a process is found by adding up the memory usage of each of
its libraries, plus the process's own heap, stack and any other mappings, plus
the stack of its 2 threads. 
Private
1293468 KB    [heap]
976 KB    /usr/lib/libkhtml.so.5.14.0
388 KB    /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6
312 KB    /usr/lib/libkdeui.so.5.14.0
212 KB    /usr/lib/libkio.so.5.14.0

Shared
4192 KB    /SYSV00000000 (deleted)
3092 KB    /usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6
2144 KB    /usr/lib/libkhtml.so.5.14.0
1316 KB    /usr/lib/x86_64-linux-gnu/libQtCore.so.4.8.6
1308 KB    /usr/lib/libkdeui.so.5.14.0

So it's about 1.3GB heap it consumes.
