Maybe this bug, closure of which is overdue (the reporter refused to 
provide the requested information):

1844628 - sluggish response in main pane after upgrading to 115 from 112
<https://bugzilla.mozilla.org/show_bug.cgi?id=1844628>;

----

For me:

1856513 - Regression: with Thunderbird 115, changes to some 
appearance-related preferences have become extraordinarily time-consuming
<https://bugzilla.mozilla.org/show_bug.cgi?id=1856513>;

More generally, 
<https://bugzilla.mozilla.org/buglist.cgi?keywords_type=anywords&classification=Client%20Software&classification=Developer%20Infrastructure&classification=Components&classification=Server%20Software&classification=Other&keywords=perf%2C%20perf%3Afrontend%2C%20perf%3Aresource-use%2C%20perf%3Aresponsiveness%2C%20&order=Bug%20Number&query_format=advanced&token=1696290149-vCOwO_0XLGwL07EczLfVIkMaxCl80xhpX9XPeRq3Uzk&product=Thunderbird&cmdtype=doit&remtype=asdefault&version=Thunderbird%20115&list_id=16741724&bug_type=defect>; 
is a mixture of open and closed performance-related bugs.
