Re: [VM] IMAP cache

(See the Starting Up section in the manual.) It is only beyond 6000 messages or so that I get to see slow downs. Cheers, Uday

If you still have the old version of the folder, please try profiling. Here are some quick notes on how to do profiling. (More details in the elp.el library file - part of Emacs distribution.) * Profiling - elp - M-x elp-instrument-package RET vm RET should instrument the whole package. (M-x elp-instrument-function and M-x elp-instrument-list or other ways to set profiling.) - M-x elp-set-master sets a master function, whose execution is profiled and nothing else. M-x elp-unset-master cancels the master function. - M-x elp-results shows the results. - M-x elp-reset-all to reset the profiling data - M-x elp-restore-all to remove all profiling. Cheers, Uday

I've included profiles of running vm-visit-folder on good and bad folders of about 450 messages for comparison. I've included the lines that most clearly differentiate the two runs. The good folder was processed in 0.6 seconds: vm-visit-folder 1 0.666869150.66686915 vm 1 0.578879675 0.578879675 vm-decode-mime-encoded-words189 0.361880942 0.0019147139 vm-update-summary-and-mode-line 4 0.3322451050 0.0830612762 vm-summarize1 0.331768543 0.331768543 vm-do-needed-summary-rebuild2 0.331305685 0.1656528425 vm-do-summary 1 0.331071934 0.331071934 vm-decode-mime-encoded-words-in-string 13870.311080336 0.0002242828 vm-mime-base64-decode-region189 0.2735256769 0.0014472258 vm-run-command-on-region8 0.260684395 0.0325855493 vm-su-summary 453 0.206757816 0.0004564190 vm-summary-sprintf 4 0.206496776 0.051624194 vm-tokenized-summary-insert 453 0.1132789349 0.0002500638 ... vm-find-leading-message-separator 907 0.0361465239 3.985...e-05 vm-insert-char 45060.0336452009 7.466...e-06 ... vm-xemacs-compatible-insert-char45060.0035975850 7.983...e-07 ... vm-left-justify-string 12 0.000122272 1.018...e-05 ... vm-right-justify-string 8 6.810...e-05 8.513...e-06 The bad folder contained 99% of the same messages and took almost 6 seconds: vm-visit-folder 1 5.902866221 5.902866221 vm 1 5.825345515.82534551 vm-summarize1 5.652573062 5.652573062 vm-update-summary-and-mode-line 3 5.6430740480 1.8810246826 vm-do-needed-summary-rebuild1 5.642558428 5.642558428 vm-do-summary 1 5.642472744 5.642472744 vm-su-summary 449 5.5901255799 0.0124501683 vm-summary-sprintf 430 5.5849337159 0.0129882179 vm-decode-mime-encoded-words-in-string 43585.453469 0.0012505737 vm-decode-mime-encoded-words182 5.4220282910 0.0297913642 vm-mime-base64-decode-region183 5.3929850379 0.0294698635 vm-run-command-on-region182 5.3591683290 0.0294459798 vm-read-folder 1 0.092051119 0.092051119 ... vm-find-trailing-message-separator 449 0.035558065 7.919...e-05 vm-find-leading-message-separator 899 0.0354277910 3.940...e-05 vm-tokenized-summary-insert 449 0.0256965510 5.723...e-05 vm-left-justify-string 12900.0252046220 1.953...e-05 ... vm-right-justify-string 860 0.0067221149 7.816...e-06 ... vm-string-width 21500.0050137250 2.331...e-06 vm-truncate-string 860 0.0038709260 4.501...e-06 ... vm-insert-char 17 5.052...e-05 2.971...e-06 ... vm-xemacs-compatible-insert-char17 1.3549e-05 7.970...e-07 Hope this helps!!
