Here's my scenario :
I am planning on using the Wireshark parsing engine in two ways :
1) process massively large captures
2) process live traffic, hopefully in the long term in a permanent manner once the memory growth of the engine can be controlled
In both cases, my automation does not care about any experts at all, it only needs the field information (length/offset/name/hierarchy/encoding...) so these experts are consuming memory for nothing in our case.
As Wireshark evolves, new dissectors get added, which might add new experts, and not having a global setting to turn them off would force us to repeatedly search for new experts appearing, which is not a great experience.
Now granted, I haven't done measurements on how much memory they consume, the current experts might not represent much, but it's hard to judge when experts can appear in any new dissector, one could appear tomorrow that significantly alters that.
Thanks,
Hassan
