Regression in current trunk?

[Angelo Graziosi]

The following happens on Cygwin, but perhaps it is general.

After that Eli fixed the status line [1], I did a new build and, really,
now the status line is OK.

But... I observe that Emacs is very slowly when one visit a big text
file (about 12M, the log of Cernlib build): it seems to hang when one
tries to move around up, down etc.. : for example, typing the down key,
it take about 1 second to move the cursor on the next line. It is almost
impossible to search (C-s) words.

If in addition I start also another Emacs, built a few days ago
(2008.08.22), and visit the same big file, it is very fast in moving
around: no delay in moving the cursor etc. To search words with C-s is
immediate.

Does it look as a regression?


Cheers,
   Angelo.
