Verified. (BTW, I aborted the initial run as it simply took too long so
actual numbers would have been much higher)

Title:
apt-get update very slow when ulimit -n is big
Status in apt package in Ubuntu:
Fix Released
Status in apt source package in Trusty:
Fix Committed
Bug description:
[Impact]
apt is slow at spawning subprocesses, as it calls fcntl() on each file
descriptor, causing significant slowdown. On my container:
0.71user 1.26system 0:01.98elapsed 99%CPU (0avgtext+0avgdata
34164maxresident)k
0.14user 0.05system 0:00.20elapsed 99%CPU (0avgtext+0avgdata
34428maxresident)k
- a 10 times difference.
[Test case]
(1) Run strace -f -c apt-cache search test >/dev/null, count getrlimit() and
fcntl() calls
(2) Upgrade libapt-pkg4.12 to proposed
(3) Run (1) again, make sure it's significantly lower.
[Regression potential]
Isolated fix in closing "unwanted" file descriptors. Has been in use for
years now, but if there were a regression it would probably be an fd leak.
[Original bug report]
I use strace to see why apt-get update is too slow,
finally I found apt-get loop 3~n to '(? , F_SETFD, FD_CLOEXEC) = 0'
