How to improve the performance of QuantShare databases?

QuantShare databases are files that are subject to fragmentation after several writes. Fragmentation, also called aging, is the inability of a file system to lay out related data sequentially.

The less fragmented databases data are, the higher the performance of QuantShare when displaying charts, screening stocks, performing analysis or backtests...

In order to reduce the fragmentation and to organize the data (EOD, Intraday, Tick or Custom data) so that the reading process becomes faster, you will need to optimize your databases.

QuantShare automatically optimize databases every 90 days. To start this process manually, select "Account" then "Application Settings".
In the "Databases" tab, click on "Schedule databases optimization for the next start" then restart the application.
In the "Application Settings" control, you can also update the optimization frequency.
