Dear Team,

Please advise us for below query related to the slow performance issue which is occurring.


•32_core CPU on Database server illogical for giving so many Cores.
•It is not only wastage of money but also against the design which is needed for DB performance.
•Its biggest side effect is that even small queries are first split into 32 parts and routed to 32 cores then their output recombined again to single output. This non-necessary split and recombination causes delays and the query that can be executed fine on low-end desktop machine are running slower .(This is 2nd main reason that EB executes in 1 hour in desktop machine and takes 2 hour in server).

Regards

I don't understand your post, but I think you need to consider lowering your "max degree of parallelism". You are probably using 0, which is the default. I'd suggest 2 or 4, but no more than 8.
