>Summary: Performance regression when splitting views (r16407)

Initial Comment:
Revision 16407 introduces a performance regression, when splitting views: it takes ~10 seconds to split a view now. Starting jEdit is also much slower.
This does not happen with r16406, but r16407.

r16407 | ezust | 2009-10-23 04:50:13 +0200 (Fr, 23 Okt 2009) | 3 lines
Fixed bug #2881152 - Bufferset Order is incorrect after a "save as".
(#2882756 - Shlomy Reinstein)

Therefore I'm assigning it to Shlomy, please investigate.

I could imagine that it's caused by a huge number of open buffers (grep -c BUFFER perspective.xml => 348).
Apart from that, I currently have 3 views open, all split in various ways.
