Hang issue if the conversation contains lots of messages, any option to only load recent messages?

[asmwarrior]

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:54.0) Gecko/20100101 Thunderbird/54.0a1
Windows_NT 6.1
Thunderbird Conversations 2.13.4

What did you do?
I have subscribe some discussion in sourceforge, such as this one:
https://sourceforge.net/p/asymptote/discussion/409349

I found that all the messages in this discussion forums are having the SAME email ID, so that all those messages are put in the same conversation in the Thunderbird-conversations. So, when I click on a new message, it takes some seconds to load the whole messages thread, especially some messages are several years ago. The whole Thunderbird are hanging for a while.

So my question is: Is there an option that I can set to let the add-on only load the recent messages, for example, only load the messages in one year?

BTW: I think Gmail web are quite smart, they don't put those messages in the same conversation, I'm not sure how Gmail web did, maybe, they group messages by email subjects?

Thanks.

I still see sometimes, TB will hang for several seconds or when I click the message, the whole thread will take several seconds to show up. My original reported issue still exits, though I see you mentioned here:

#1014 (comment)

Is it possible the compare the subject title string or limit the time?
Thanks.
