When exporting, the 'Queueing Export' step hangs for a long time:
By default, Scroll Word Exporter can only perform 4 exports at the same time. Your export is queued because more than 4 exports are being executed at the same time.
There is a maximum of 4 parallel exports because Scroll Word Exporter uses a separate pool of worker threads that handle export requests – and by default, the pool contains 4 threads.
Confluence administrators can configure the size of this pool by setting a custom Java System Property in the Confluence startup scripts.
Please note that increasing this number may have a negative impact on your overall Confluence performance.
There's no rule of thumb for the ideal number of threads. Please always test the performance of your Confluence system after any change in the number of threads.
The CPU time is limited and the more export threads you configure the less CPU time is available for other threads, for example the web worker threads that handle the Confluence web requests when opening a page.

Don't forget to restart Confluence after setting the system property.
