Hi,

As can be seen we have managed to make a significant improvement from 1.10.6

That's awesome, I hadn't realized all those little changes had added up so much.

Some stuff that might still be interesting to look into is xml parsing

Tvb_parse_get()

 

In tree_data_add_maybe_interesting_field() change the g_hash_table_new and g_ptr_array_add() to use wmem based functions.

 

Change p_add_proto_data() to use wmem based functions.

 

You may also want to look at using Jakub's new proto_tree API (passing the hf vars directly) since it uses one fewer layer of indirection. I think (but am not sure) that it might be a bit faster than the current one.

Regards

Anders
