Maximum Open Files

You requested maxclients of 10000 requiring at least 10032 max file descriptors.
Server can't set maximum open files to 10032 because of OS error: Operation not permitted.
Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

	Copies all keys from the source Redis host to the destination Redis host.
	Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
	restricted (e.g. on Amazon ElastiCache).

	The script scans through the keyspace of the given database number and uses
	a pipeline of DUMP and RESTORE commands to migrate the keys.

	Requires Redis 2.8.0 or higher.
