Hi guys I have couple questions I've asked in the past but cant quite
find the answers for them
1. Hoiw can we get memcache to use more of the allocated memory. On
machines that im setting it to use 6886 megs it always looses about 1g
that it never users.
2. What is a good number to allocate on a machine based on its total
ram. I want to use as much memory as possible since the machine is
dedicated only to memcache. on a machine with a total of 7872040
kbytes i'm starting it with 6836 megs which comes out to total of
7168065536 bytes 7000064Kbytes leaving in theory 872040K to deal with
OS but i've still experienced times where the kernel kills the process
because it runs out of memory.
3. how much should i allocate of memory per connection?
I'm using Amazon EC2 so im trying to get as much performance out of
each machine as possible. My instances at this point are using about
6800 connections at peaks.
