I have Ubuntu 14.04.1 install on AWS and it was getting slower and slower Not knowing what to do I updated and upgraded my system It did not help

Testing disk usage (df -h) I get

Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      7.8G  5.9G  1.5G  80% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            492M   12K  492M   1% /dev
tmpfs           100M  356K   99M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            497M     0  497M   0% /run/shm
none            100M     0  100M   0% /run/user

It takes me some 6-7 minutes to login using PuTTY (use to instant) Where do I start?


  • I think it's not generaly ubuntu problem. Thing you described looks like reverse dns problem. See askubuntu.com/questions/246323/… – user3417815 Apr 29 '15 at 12:33
  • And please correct this, what becomes slower? Login, performance, disk activity? – user3417815 Apr 29 '15 at 12:33
  • Everything got slower: Login, web access, upload of files... I looked at memory usage and it looks bad, here it is: KiB Mem: 1016256 total, 948984 used, 67272 free, 110012 buffers KiB Swap: 0 total, 0 used, 0 free. 295940 cached Mem I will now look at the revers DNS Problem as suggested Thanks – ShimonD Apr 29 '15 at 13:13

Seeing that all resources are short (memory and disk) I upgraded my image to a new server with 4GB of ram and double the disk size and everything is back to normal.

Nice and fast

Thanks for all your help.
