Hi! I was thinking about which hardware and software attributes are the most important factors for improving performance of Emacs and/or Org-mode. The things I want to improve are
(1) startup time of GNU Emacs (nice to have, no priority) (2) using Org-mode agenda with approx. 20 Org-files (3) using agenda view including archive files The Org-mode files I regularly use in (2) contain 15,000 to 25,000 lines. The org_archive files contain more lines, three of them 40,000 to 130,000 lines with PROPERTY-drawers[1]. The biggest performance increase I'd like to see in moving in my normal agenda (approx. 2-3s from one day to the next) and in my agenda including the archive files (approx. 4-8s from one day to the next). Usually, it is worth waiting :-) On my system [3] I notice 100% load on one of my two cores when Emacs is generating the agenda views. So I am not sure whether more cores could increase the performance. Probably a faster CPU? Is there something that makes Emacs use multiple cores in parallel? We did some performance testing [1] for Memacs [2] but this only tested a static situation on given platforms. What do you think are the most important factors? - CPU speed (of one core) - type of CPU - # CPU cores - 32bit kernel vs. 64bit kernel - faster I/O (through HDD->SSD or even faster SSD) - choice of the file system (optimized for something? what?) - operating system - possible ELISP optimizations (are there any besides compiling?) Probably you already have an idea of a system which is designed to be optimized for Emacs/Org-mode/Agenda ...? How does it look like? :-) ... very curious about your thoughts ... 1. https://github.com/novoid/Memacs/blob/master/docs/performance.org 2. https://github.com/novoid/Memacs 3. lenovo X200s, Core 2 Duo, SSD, Ubuntu 11.04, Gnome 2, GNU Emacs 23 -- Karl Voit
