Re: scale up (postgresql vs mssql) - Mailing list pgsql-performance

hi,

thanks a lot to all of you for your help.

(i'm sorry i did not know how to reply to a certain message)

i found that the best number of active connections is indeed 8-10. with 8-10 active connections postgresql did ~170 "account-id"s. this is still only half of what mssql did, but it now makes sence, considering that mssql works close to twice faster.

i "played" with work_mem, shared_buffers, temp_buffers. i ran the tests with both of the following configurations, but no significant difference was found.

thanks again for any more help.
