I have a docker-based installation of Alfresco Community 7.1 and a load balancer with 4 Transform containers (using a proxy to balance between the 4 containers).
And every time I upload an Excel spreadsheet, it takes time to generate the thumbnail and also the preview of the document in Alfresco Share. This time can take from 5 to 10 minutes, and I've had up to 30 minutes of time, causing Alfresco to overload and stop.
My server has 64 Gb Ram and 16 Cores.
I configured alfresco-global.properties not to generate thumbnails for all the files and I was testing settings so as not to generate previews of the xlsx files (for example) but it didn't work.
After applying these configurations to alfresco-global.properties, is there any further procedure to do?
What can I do to not generate a thumbnail of .xlsx files and not generate the rendition of these files, as well as the non-preview of these files too?
This should not take the amount of time you have mentioned. With pretty much ootb settings itself i tested a 10 mb xls file and it got the thumbnail within fe seconds. System config is 4 CPU and 16G RAM.
I am not sure what properties you were setting. but with 7.1 there is no legacy transformer. So all these settings has to be done in repective transform engine. e.g. for docx, xlsx, etc it would be lifreoffice.
