 # Comparisons.PostgreSQLVSDoublets
 
-The comparison between PostgreSQL and Doublets
+The comparison between PostgreSQL and LinksPlatform's Doublets (links) on basic database operations with objects (create table, read table, delete table, update table).
+All benchmarks ran with 3000 links in background and 1000 in active use (i.e. insert, delete, update).
+
+## Operations
+- **Update** – basic update operation
+- **Each All** – take all links matching `[*, *, *]` constraint
+- **Each Incoming** – take all links matching `[*, *, target]` constraint
+- **Each Outgoing** – take all links matching `[*, source, *]` constraint
+- **Each Concrete** – take all links matching `[*, source, target]` constraint
+- **Each Identity** – take all links matching `[id, *, *]` constraint
+- **Delete** – basic delete operation
+- **Create** – insert point (link with id = source = target)
+
+## Results
+The results below represent the amount of time (ns) the operation takes per iteration.
+- First picture shows time in a pixel scale.
+- Second picture shows time in a logarithmic scale.

+
+## Conclusion
+As we can see in this comparison, Doublets are blazingly faster than PostgreSQL in basic database operations.
