   Lines 608 to 618 in 01a6979

   	Status FloydImpl::ExecuteCommand(const CmdRequest& request,
   	CmdResponse *response) {
   	// Append entry local
   	std::vector<const Entry*> entries;
   	Entry entry;
   	BuildLogEntry(request, context_->current_term, &entry);
   	entries.push_back(&entry);
   	response->set_type(request.type());
   	response->set_code(StatusCode::kError);
   	uint64_t last_log_index = raft_log_->Append(entries);

   
   I mean before writing to log, entries at L618 will always contain only one item. I suppose we can merge multi threads' write operation into entries.
