cedric pushed a commit to branch master.
commit 096a8ece9f056236e915342eeadbcdf5dc025081
Author: Jean-Philippe Andre <[email protected]>
Date: Wed Jun 26 16:31:38 2013 +0900
evas/cserve2: Set default LRU size to 4Mb or env-based
The LRU should not be limited to 0 byte otherwise all scaled
images will be dropped and reloaded constantly, killing the
performance.
The size is inspired from the scalecache's size of 4Mb.
Variable: EVAS_CSERVE2_SIZE (number in Mb)
