A lot of Capture Attribute nodes in sequence can create a huge number of attributes.
If these attributes are not used, they must be removed.

The speed of the Capture Attribute and Store Named Attribute nodes is now identical (for the better).
There are also no extra RAM usage now.

Generally looks good. Can you provide some updated performance numbers for the .blend file in the bug report?

Might need to be careful here, removing an attribute may invalidate data referenced by other AttributeIDRef (mainly the name). Better first gather the names of all attributes to remove, store them as std::string and then remove them in a second loop.
