I have prepared a new machine for testing, and I don't see any slowdown by mounting devpts. Total mounts on it: # wc -l /proc/mounts 153481 /proc/mounts # fgrep -c devpts /proc/mounts 10231
On my other servers there're slowdown already by this number of: # wc -l /proc/mounts 49889 /proc/mounts # fgrep -c devpts /proc/mounts 3323
But the first box is totally empty, others are in use, may be this matters?
