Subject long waiting times on routervm for savepassword and DhcpEntryCommand's
Date Wed, 01 Jun 2016 09:10:30 GMT
Hi Developers;
I could find any answer from Cloudstack User Mailing list, i am forwarding
my mail to the development list, thanks for all answers who has experience
on high capacity virtual router usage.


Today i noticed that my vm creation commands takes a little bit long then
before. When i check the logs i noticed that router vm takes too much time
like 4 seconds for each savepassword and DhcpEntryCommands.

We are using advanced networking with security groups enabled for ACS 4.8 .
It looks like when ip address usage increases(100 ip addresess for one C
Class network) for each guest network block, router vm responds slower than
the old days.

We are using default compute offering for virtual router, my plan is to
change to default offering for virtual router vm to 512 mb ram & 2 core cpu
and increase cpu shares and restart virtual router.

Are there any other cleanup procedures or other ways to speed up
savepassword and DhcpEntryCommands like disable logging or any other clues
would be helpful. Because of this long waiting times on 2 commands total vm
creation time takes longer then expected.
