# Do not use named path (unless it is required)
<a name="best-practices-content-10"></a>

 Named path in a query always comes at an additional cost, which can add penalties in terms of higher latency and memory usage. Consider the following query: 

```
MATCH p = (n)-[:commentedOn]->(m)
WITH p, m, n, n.score + m.score as total
WHERE total > 100 
MATCH (m)-[:commentedON]->(o)
WITH p, m, n, distinct(o) as o1
RETURN p, m.name, n.name, o1.name
```

 In the above query, assuming we only want to know the properties of the nodes, the use of path “p” is unnecessary. By specifying the named path as a variable, the aggregation operation using DISTINCT will get expensive both in terms of time and memory usage. A more optimized version of above query could be: 

```
MATCH (n)-[:commentedOn]->(m)
WITH m, n, n.score + m.score as total
WHERE total > 100 
MATCH (m)-[:commentedON]->(o)
WITH m, n, distinct(o) as o1
RETURN m.name, n.name, o1.name
```
