I tried inserting 10 values of size 1000000 bytes. I am able to insert all 10 values but I guess only the last 3 are present in cache since I am getting cache misses for the first 7 key-value pairs. Is there a flag that we have to set in the memcached configuration file (I currently have the '-m' option set to 2048)
