Benchmarks

Measured runtimes for the core operations of the Ocelescope base tool on public object-centric event logs: import, export, filtering, and discovery.

Each configuration was run 5 times on the machine below, and the reported value is the median in seconds. Charts show these medians; the complete per-run numbers are in the All runs table under each section.

Export

Median export time by file format Native OCEL exports. The flattened xes export writes a single object type and is listed in the table below only.

• xml
• json
• sqlite

Logarithmic time axis: bar length is not proportional to the value.

All runs

A blank Flattened type means no flattening (native OCEL export).

Filtering

Median filter time and how much each configuration removed Nine filter configurations.

• Runtime
• Events excluded
• Objects excluded

Each panel has its own axis: runtime is linear in seconds, exclusions are a logarithmic count, so bar lengths only compare within a panel. A configuration that excluded nothing shows 0 at the axis start.

Discovery

Settings: OC-DFG at frequency threshold 1.0, Inductive Miner (flattening) at frequency threshold 0.8. The two largest logs were pre-filtered first; the sizes below are after filtering. aoe2 was reduced to its top 80% activities and 90% objects; steel logistics by a two-part exclusion filter listing 87 object types and 587 activity types explicitly (largely storage locations, installations, and movement events).

Median discovery time by algorithm Logs ordered by size.

• OC-DFG
• Inductive Miner

Logarithmic time axis: bar length is not proportional to the value.

The Events and Objects columns are the size of the log after the pre-filter was applied.
