It is executing the shell command defined at recording.c line 34.

This has been discussed here before.
You can run than same command outside vdr and time it, e.g.:
     time find /video -follow -type d -name '*.rec'

Then tune your system so this command runs faster.
Maybe you have other stuff under your /video path.
That would slow things down.

Linux has cached the directory entries.
I'm surprised it still takes 7 seconds.
Maybe you do not have enough memory.
If I remember it correctly, it takes abut 2 seconds here.

Total agreement. That would be very nice.



Also, I believe that Klaus has plans to internally buffer the
names of the recordings. I am not sure if that idea is bullet-proof,
as of course you could remove, rename, copy, add, etc. recordings
outside vdr.
