Re: Lazy printing in tabulated-list-mode

Here we go. So:

41% of the samples were in garbage collection. I missed that the first
time, but it looks like a pretty big deal.

8% are in sorting the entries.

7% disappear somewhere inside tabulated-list-print-entry.

36% are spent inside tabulated-list-print-col (report snippet pasted
below). Out of which:

11% are completely unacounted for

9% are in the following `if' form, but only 2% and 1% are spend on the
`apply' and the `insert'. So I think that means `get-text-property' is
eating up 6% here?

(if (stringp col-desc)
    (insert (if (get-text-property 0 'help-echo label)
            label
          (propertize label 'help-echo help-echo)))
      (apply 'insert-text-button label (cdr col-desc)))

12% are in a `progn', which I think corresponds to the body of this
`when', but I don't know what's responsible for this.

(when not-last-col
        (when (> pad-right 0) (insert (make-string pad-right ?\s)))
        (insert (propertize
                 (make-string (- next-x x label-width pad-right) ?\s)
                 'display `(space :align-to ,next-x))))
