Follow up : Is-there-a-way-to-bypass-Tenant-for-Translations , Performance issue #1987

thomas.blotiere@abraxas.ch created 3 years ago

Hello,

I have followed the solution that has been suggested as an answer of my initial question here : https://support.abp.io/QA/Questions/1642/Is-there-a-way-to-bypass-Tenant-for-Translations

Technically, this is working fine but what happens is that my code now loads up to 33 ressources and the impact on performance is significant when the user changes of tenant or of language.

I had to disregard this solution because of this performance issue.

Sure I am sure I can remove a few ressources from loading but a few less will not change much of the performance issue.

Can this code be improved ? Or is there a better way to do achieve the same result, that is to access translations independently of the tenant ?

Thank you

Thomas
