Re: shared_buffers 8GB maximum

[Vitaliy Garnashevich <vgarnashevich@xxxxxxxxx>]

When we did calculation of some analytic tasks, then increasing shared_buffers had negative impact on speed. Probably hit ration was too low after change, but the maintenance of shared buffers (searching free blocks) was slower.

What was the size of shared buffers when slowdown happened (approximately)?
