Hey Denis, thanks for the response...<br>
<br>
I was just using apt to install isc-dchp server on ubuntu 14.04<br>
Server is quad core xeon with 8 gigs of ram with a software raid 1
disks<br>
<br>
But maybe i should consider your way...<br>
<br>
I was just doing some testing using a ramdisk for the
/var/lib/dhcp/dchpd.leases files<br>
<br>
Our leases are short for special reasons... 20 minutes<br>
<br>
so on a dev machine i created a ramdisk of 2 gigs, and backup the
leases files to a hard disk each 5 mins, and on restart the
/etc/init/isc-dhcp-server.conf will copy the files from backup to
/ramdisk then start dhcp<br>
<br>
on dev it works fine... but i may consider your way now...<br>
<br>
we tend to shy away from compiling stuff.. :(<br>
<br>
Even after 24 hours after start of the peer never came out of
recovery mode, not sure why..<br>
<br>
Currently we made dhcp-2 a standalone server and it currently has
217335 leases in it, but i will need to double that at least in
coming weeks..<br>
<br>
Server is currently ....<br>

I will try your suggestion on dev machine<br>
Do you use or know of a tool that i can use to simulate dhcp request
for testing on my dev machine?<br>
<br>
Thanks for your help!<br>
