If ecb-source-path contains directories with many files and
subdirs, especially if these directories are mounted net-drives
("many" means here something > 500, dependent on the speed of the
net-connection and the machine), actualizing the sources- and/or
directories- buffer of ECB (if displayed in current layout!) can slow
down dramatically. If this is a problem the contents of certain
directories and also the contents of the sources-buffer can be cached
which increases the speed a lot. See the option
ecb-cache-directory-contents.
IMPORTANT: The full speed-advantage of this cache-mechanism is only
available if ecb-show-sources-in-directories-buffer is
nil, i.e. sources of a directory are displayed in the
ECB-sources-window. The reason is that only with a sources window the
tree-buffer contents for the sources can be cached (i.e. the
buffer-content of the ECB-sources-window) whereas with sources
displayed in the directories buffer only the disk-contents of a
directory are cached - which increases speed too but not so much as
with sources displayed in the extra window ECB-sources.
The cache of a directory can be only refreshed by a POWER-click (with mouse or keyboard) onto the related directory-node in the directories-buffer of ECB (see Using the mouse).
See also the option ecb-cache-directory-contents-not. Here are
some useful settings for both of these options:
ecb-cache-directory-contents to ((".*" . 500)) and set
ecb-cache-directory-contents-not to nil.
ecb-cache-directory-contents to (("^/usr/.*" . 200)) and
set ecb-cache-directory-contents-not to nil.
ecb-cache-directory-contents to ((".*" . 500)) and set
ecb-cache-directory-contents-not to ("^/usr/.*").
Another way for getting a faster overlook for large directories with
many source-entries is to apply an online-filter to the
sources-buffer. This can be done via the command
ecb-sources-filter or via the popup-menu of the sources-buffer.
