There is 8 GB RAM on the server, and on first access apache bench doesn't show any failed requests, but if I execute the program again, I see that number of failed request show up, this is something that I couldn't understand as why didn't the number of failed request show on the first run and then appears every subsequent run (Total request for each run : 10,000 and 200 cc).
Are these apache errors or errors in memcache? If you are running a high concurrency in apache benchmark you may be running the server out of sockets or some other resource.
"Perhaps with memcached running you don't have enough memory to ...". this is not the case in any which ways, have checked the memory and had that been an issue even file IO would have more or less given me the same performance.
I think you are missing the point that if you had just enough room for the data in the file buffers without memcache, then allocate a portion to memcache, neither one would have enough space and both would have to continuously reload the data as it is evicted.
