Why is the query speed of the second method faster?

1. SqlQuerySpec sqlQueySpec = new SqlQuerySpec();
   sqlQueySpec .setQueryText("select * from c where c.name = @name");
   SqlParameter sqlParameter = new SqlParameter();
   sqlParameter.setName("@name");
   sqlParameter.setValue("Tom");
   List params = new ArrayList();
   params.add(sqlParameter);
   sqlQueySpec .setParameters(params);
   cosmosAsyncContainer.queryItems(sqlQueySpec , queryOptions, Object.class);

2.SqlQuerySpec sqlQueySpec = new SqlQuerySpec();
sqlQueySpec .setQueryText("select * from c where c.name = 'Tom'");
cosmosAsyncContainer.queryItems(sqlQueySpec , queryOptions, Object.class);

It is not. Make sure in testing to look at latency after warm-up. The first few calls will have to open new TCP connection, process SSL handshakes and download metadata (that is cached). Best-case you also provide the PartitionKey on ComsosQueryRequestOptions - that in combination with approach 1) will remove one necessary i/o operation (to retrieve query plan) - if you don't know the partition key this is a cross-partition query that will need to reach out to all partitions - which won't be efficient - but same for 1) and 2)
