A series of tests where I have mixed read/write ratios. In particular:
30% read, 70% write
50% read, 50% write
70% read, 30% write
with multiple increasing numbers of threads.
And, how many databases ?
I assume the recommendation is based on one database? In my deployment, I have
3 relatively large databases (~400 000, ~500 000, ~800 000), so since better
performance at the reduced thread number is probably due to reduced database
contention, 24 threads may be more appropriate for me?
Or, should the number of threads be configurable at the database level ?
