I have few tables, and I have pre partitioned the tables. I would like to
achieve reduced latency. I am just thinking of placing related regions on
the same region server/host. For example, table 1 contains 3 regions
[a,b,c], and table 2 contains 3 regions[x,y,z]. (a,x) contains the data for
some group of users, (b,y) contains the data for some group of users, and
(c,z) and so on. 

If I have two region servers, instead of placing [a,b,c] on one server, and
[x,y,z] on other server, is there an advantage of placing related regions
(a,x), (b,y), (c,z) among the region servers?

Note: I also make sure the regions will not be divided further, or there
will be manual intervention needed to divide the regions further.
