Answer / Solution

The speed of DataCentral depends on many factors.

The speed of the indexing of documents depends on:

• the number of actually indexable files (xlsx and txt are indexable, but exe not)
• the size of the files
• the type of the files (txt files are usually faster than xlsx/pdf)
• the hardware (RAM and CPU, incl. the number of cores)

For a small drive, DataCentral can be done within minutes, for larger ones, it can take hours and for very large drives with multiple TB of indexable files (exe files, images, ... don't count), it can even take days. Smaller scans lead to smaller indexes, which can usually be searches through faster.

SpaceObServer shows a progress and an estimation for the remaining time of the indexing in the "Configure scans" window in the "State" column of the scan.

The performance of a search is usually faster than without DataCentral and depends on:

• the number of the files found by the search
• the serach term and its frequency in the index
• the network between the UltraSearch client and the DataCentral server

We aim to execute most of the searches within a few seconds.
