Re: [PacketFence-devel] Pfbandwidth Bottleneck

[Durand f. <fd...@in...>]

Hello Till,

We probably can do something and save the stats via pfqueue 
(inline_accounting_update_session_for_ip in pfqueue).

It need a little bit of dev (really few).

also can you check one the db side if there is no issue ?

Regards

Fabrice
