Can you run strace groupadd xyz and get an idea what takes so long time?
I ran: strace groupadd xyz 2>straceout
I looked at the file straceout and then did: grep -v mremap straceout >noremap
root@s2 ~# ll straceout noremap -rw-r--r-- 1 root root 6281700 Feb 17 08:40 noremap -rw-r--r-- 1 root root 169173793 Feb 17 08:31 straceout
The straceout file is chock full of these lines where the center numerics change every so often:
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
mremap(0xb7d87000, 147456, 147456, MREMAP_MAYMOVE) = 0xb7d87000
The difference in size between straceout and noremap is how much mremap output there is.
Is this remaping RAM?
