Re: MySQL Partitioning showing low performance

I agree with Rick, since there is an index on (column2,column3...) you will hardly gain anything from partitioning on this query (unless you have problem with getting it all into the bufferpool, where partitioning could help by having the hottest partition there).

Also I wonder if you could try 5.6, since I think you are affected by bug#37252, which is fixed in 5.6. Then it should at least have similar performance as a non partitioned table. I would appreciate some feed back on the fix!
