Predictor Data Size Restrictions
The following table shows the average and maximum data sizes for the Predictor resource.
| Parameter | Average value | Maximum value |
|---|---|---|
| Number of products in the product catalog | 50,000 | 500,000 |
| Number of cases to build the model | 30,000 | No limit other than the amount of available memory |
| Number of transactions per user | 20 | Total number of properties |
| Size of computed model | 100 KB | Limited by your database limitations |
| Maximum number of properties predicted per call | 10 | Total number of properties |
Performance Criteria for the Predictor Resource
The following table shows the performance criteria for the Predictor resource. The criteria are based on the average numbers defined in Data Sizes and Limits for the Predictor Resource.
All numbers are measured on a dual-processor 550Mhz Pentium III with 512 MB of RAM Web server for making Prediction, and quad-processor 550Mhz Pentium III with 2 GB of RAM Database server for building Analysis models and to call LoadModelFromDB(). Client computers are 400 MHz Pentium II with 128 MB of RAM.
| Criteria | Component | Minimum | Maximum | Average |
|---|---|---|---|---|
| Latency to make prediction | Client | 0 milliseconds | 20 milliseconds per prediction call | 10 milliseconds per prediction call |
| Throughput of prediction requests | Client | 30 predictions per second per CPU | Not applicable | 90 predictions per second per CPU |
| Load model from database | Client | Not applicable | 3.6 seconds | 3.4 seconds |
| Service start time | Service | Not applicable | 20 seconds | 5 seconds |
