At this time, b2evolution is not really designed for handling 50 million blogs simultaneously. Do you really need that many?

yah I need that , this cms is really awesome , and with some change's it can be handing over 50 million blog , but if you have idea to fix this problem please tell me .

And I am going to security pentest of this app , after ending the test i will tell you results ,

thank you for this good cms

I don't have a specific idea at this time. It can definitely be done. It will require finding the places where we load too many blogs into memory at once and change that.

We have stated that in the past. This is why in many place you need to enter a blog ID instead of choosing from a select list. But we haven't finished. A lot of more urgent tasks have emerged in between.

We are always interested in pentest results. Thank you.
