Re: [Orgmode] org-shifmetadown/up are slow
Hi Samuel, On Jul 8, 2009, at 7:07 AM, Samuel Wales wrote: I think that some of this is slow for inherent emacs reasons. Simply doing down arrow can sometimes be slow. Yes, if there is *lots* of hidden text the cursor has to jump over. However, moving subtrees is very slow. Dp you think it's mostly outline-mode? Is it possible to defsubst after the fact? Please pull from git, this problem should have disappeared, I simplified the cleanup of the display after moving a subtree which became *very* expensive for entries with very many siblings. So the reason was Org in a way, but the reason why this operation was slow is because outline functions used are slow. What I have done now as well is advising outline-end-of-subtree to use my own version when in Org-mode, so that any outline commands using it will now be much faster. The reason why outline functions are so extremely slow for some operations are: - they have been written in full generality, with possibly weird strings as outline headings, so they need to find each and every heading and compute the outline level. Org, on the other hand, knows that the headline level is directly given by the number of stars and can directly search for the right kind of heading that will terminate the subtree. - Outline functions have been written with book-like structure in mind, i.e. with a limited number of nodes. Large and deep lists as we have them will cause this code to perform badly. HTH - Carsten Thanks.

Re: [Orgmode] org-shifmetadown/up are slow
I think that some of this is slow for inherent emacs reasons. Simply doing down arrow can sometimes be slow. However, moving subtrees is very slow. Dp you think it's mostly outline-mode? Is it possible to defsubst after the fact? Thanks.

[Orgmode] org-shifmetadown/up are slow
I frequently rearrange headlines with org-shiftmetadown/up. It is faster (in the human sense) than kill and yank or refile if the place I want to put them is underneath a sibling. However, it is sometimes slow, taking a second or two per command. This occurs when there are large trees around. Is this something that can be sped up, or is that impossible? Here is a profile generated with mostly medium-sized trees (I will have about thrice that size in some cases) in case it helps. I did elp-insrument package org then a bunch of the relevant operations then elp-results. Please tell me if there are better ways to profile. Thanks.
