In any case, you could profile the old and new version of vdr and
see if
there is any obvious difference.
I'll have to take that into consideration. I'll have to download the
old version and all that :)
I was unsuccesfull with setting up an environment where I could run
vdr-1.3.22. It just exits with exit code 2 with no other explanation
in. It tells me to turn off NPTL by setting LD_ASSUME_KERNEL=2.4.1
and then all I get is "error while loading shared libraries" to
about any command I try. And then "cannot open shared object file: No
such file or directory" and depending on the command the library file
varies.
So no comparison :(
This thread changed to talking about different issues like ati and xine
which are actually far from the original meaning of my post. I still
have this performance issue. I could not make the comparison with
earlier vdr version but I did do some profiling.
I did a seven minute session where I had 5 test recordings which started
one minute apart and ended at the same time. After each recording had
started I tested the responce of remote by just pussing menu button.
After three recordings there began to be delay in menu appearance and
after fourth recording the menu came up in pieces and after fifth
recording there were no menu or if it ever did appear after several menu
presses it was incomplete. This can be seen in the log (timeout waiting
in LoadBitmap). Playback of a recording started to have small problems
after third recording started and with four and five simultaneous
recordings you really do not want to wath a movie like that.
This is the log during the test:

During the test CPU idle was over 90% all the time. I used oprofiler
during the test and these are the results:

I've done the test with three different settings, one with a PIII733MHz,
one with AMD Sempron 3000+, and one with Intel Celeron D 3,2GHz and the
results are quite similar. With PIII and AMD I used one dvb-c card (DVB:
registering new adapter (Technotrend/Hauppauge WinTV DVB-C rev2.X)) and
with Celeron two dvb-c cards (DVB: registering new adapter
(TT-Budget/WinTV-NOVA-C PCI) and DVB: registering new adapter
(Technotrend/Hauppauge WinTV Nexus-CA rev1.X)). I use the ff cards video
out.
I had only vdr-1.4.5-2 with no plugins or patches. I also used a
home-brewed ir receiver with lirc.
And I used the latest firmware.
Can anybody use this data to tell me where the problem lies.
