For the love of Foo, please fix page management for once and for all. Quite frankly, I'm a bit shocked and upset that nothing made it into the 2.1 release.
I manage a very large-scale patient education site that receives over 10k visits per day. We are approaching 600 static pages (not including our daily "posts" in the magazine section of the site).
WordPress page management fails miserably: anything above 100 pages and php execution time becomes an issue. We've had to constantly update the hacked page management page in order to use it at all.
This has been an issue for over a YEAR now, not just months. There are at least three forum threads relating to this issue, with no resolution. What's more, I can't find even one ticket in Trac that refers to the problem, and because new ticket creation has been locked down, I can't even notify anyone as to this very well-known issue that no one seems to want to fix.
Does WordPress *want* enterprise users? If so, stuff like this really should be fixed. I really like WordPress, but for us, this is a deal-breaker.
