Can you post the XML query plan here https://www.brentozar.com/pastetheplan/.
In answer to your question, partitioning is generally not a query performance enhancement tool. With proper indexing, partitioning will not help query performance.
Partitioning a table that small, will not have any performance impact. Partitioning is really only useful for loading/unloading large amounts of data. For example, billions of rows per month, and you only want to keep a rolling 12 months of data in the table.
