Description
Simply listing issues is very slow, the more issues are listed and the more columns are, the slower. That is 10-20 seconds for displaying 300 tickets with all columns. While the comma delimited output of the same query just takes a fraction of a second. Speed also does not seem to improve by repeating the request.
The problem (to a lesser extent) can be reproduced with trac.edgewall.org too. I suspect its the same issue as the symptoms look the same. But iam just guessing here
heres an example:
