sql2008 R2 soft NUMA advantages

Hello guys,
I have a server running with only 1 Numa Node with 16 logical  processor. I'm thinking to divide them by creating soft NUMA. For examples Creating 4 Soft Numa to represent 4 processor on each soft numa.
If I'm doing this, does it means I'm going to have 4 I/O thread and 4 Lazy writer  thread for sql server  and thus increase the performance of the sql server ? ?

I know there are oposite recommendations like "Configuring four soft-NUMA nodes provides four I/O threads and four lazy writer threads, which could increase performance" from https://www.sqlskills.com/blogs/jonathan/sql-server-and-soft-numa/ 
but in my opinion it will be the opossite unless you plan to run multiple SQL Server Instances on that same server so SQLInstance 1 runs on NUMA1, SQLInstance2 runs on NUMA2, etc..
This is because "...It is faster to access local memory than the memory associated with other NUMA nodes."

This is recommended configuration where you will see the same thing I mentioned above: https://msdn.microsoft.com/en-us/library/ms345357.aspx
You should also look at best practice for parallelism as this is a way more important factor from my personal experience on later SQL (SQL2005+)  server versions:

Aside that you must look at SQL licensing model depending on which edition you run to take advantage of using the max number of CPU's (logical or not).
