teloniatis is still having a problem:
Hi again,
Sorry for late response.
Indeed the mentioned change with rru buffers decreases a lot the memory
footprint of (de)compressor objects.
However, still the memory allocation is very high, because context's memory
footprint is also too high.
One of the reason for high needed memory is for compressing lists of IPv6
extension headers, for which I am not so familiar yet.
However, by modifying some constants (eg. ROHC_LIST_ITEM_DATA_MAX) in
"common\rohc_list.h", we managed to decrease size of structs list_(de)comp from
70224 to 2064.
But my questions is why to reserve memory for lists if no IPv6 support is
needed? And I am referring to decompressor's context, since during compressor
context initialization there is a check for IP version, and
"rohc_comp_list_ipv6_new" is called only for IPv6.
Why not having the same check when init decompressor's context, when calling
"rohc_decomp_list_ipv6_new" respectively?
Regards,
Evangelos
