Do you have one for sending remote-write data?  The one you linked 
is RemoteWritehandler which is for receiving.

I expect to show significantly increased memory allocation.
Unfortunately the remote-write structure with a struct for every name-value 
pair and all labels repeated is maximally bad for this.
