> how do you think is it possible to set memcache_servers = *local_ip*:port in keystone.conf? or it can lead to some issues?

It will definitely lead to issues. And should not be done.

Last time we tested things on scale, emulating production-like load, performance was worse, but acceptable. It is also known issue that first requests after controller shutdown take more time. I suggest you to make you not 10 queries, but 100 or 150, probably in parallel.
