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. Click on the "Help" button in the upper right corner.) Have a nice day :) Thomas
