Performance
We ran two experiments on a `c7gd.12xlarge` instance using the [LDBC SF300 Comments `creationDate` Parquet file](https://blobs.duckdb.org/data/ldbc-sf300-comments-creationDate.parquet) file (also used in the [microbenchmarks of the performance guide](#docs:guides:performance:benchmarks::data-sets)).  
<div class="narrow_table"></div>  
| Experiment | File size | Runtime |
|:-----|--:|--:|
| Loading only from Parquet | 4.1 GB | 3.5s |
| Creating local table from Parquet | 4.1 GB | 5.1s |  
The “loading only” variant is running the load as part of an [`EXPLAIN ANALYZE`](#docs:guides:meta:explain_analyze) statement to measure the runtime without account creating a local table, while the “creating local table” variant uses [`CREATE TABLE ... AS SELECT`](#docs:sql:statements:create_table::create-table--as-select-ctas) to create a persistent table on the local disk.
