@ seth-arnold

I set ulimit 2560000 on my machine,here is the test.

My question is Why in new version of apt-get,it's must check file descriptors?

root@dev2:~# ulimit -n 2560000
root@dev2:~# time apt-get update > /dev/null

real 0m32.587s
user 0m19.211s
sys 0m11.127s
root@dev2:~# ulimit -n 1000
root@dev2:~# time apt-get update > /dev/null
