A clarification:

While the first part of my mail described slow access on network volumes, the last part (see below) is about a local (non-SSD) hard disk. So the slowdown is not limited to network file systems.

Actually, anohter customer just contacted me who noticed the same slowdown at even greater intensity when he upgraded from 10.7 (I believe) to 10.11. His disk is near-full, so probably has a highly fragmented directory, and he has only 8 GB of RAM (while I have 20). Acitivity monitor shows that the "Cached Files" is about 2 GB in his system, and about 5 on mine. So it seems that recent OSX versions limit the file/dir cache to a percentage of the RAM, whereas old systems used it all when available. Is that so?

Thomas
