[Pkg-mc-devel] Bug#805495: mc: Very slow opening of an ISO file

[Thomas Schmitt]

Hi,

as the developer of xorriso i am unhappy to see that
its mere existence makes mc slow with ISOs.
Even if it is not to blame directly.

So i would propose to just disable for now the use of
xorriso for inspecting ISO filesystems by mc.

In general xorriso would be well suited for such a job
only if run in dialog mode. It has the habit to load 
the whole directory tree into memory before it performs
commands like -lsl. The more such commands it performs
in one run, the more beneficial is the pre-loading.

If xorriso is used as 1:1 replacement of isoinfo, then you
need quite a simple ISO or quite a fast computer to get
a comparable performance.


(See xorriso-tcltk for an example of dialog-under-GUI:
  http://libburnia-project.org/export/head/libisoburn/trunk/frontend/xorriso-tcltk
 Needs Tcl and Tk >= 8.4, optionally: Tcl/Tk package BWidget.
 Start without any arguments.

Have a nice day :)
