Network performance problem (Possibly BGP related)

[alanfs]

Hi,

I have a pair of pfsense machines in a carp pair running a full BGP routing table and I am seeing some network performance problems.

Fetching a file from the internet whilst on the firewall, I get speeds of 23 MBps (Briefly, until the CF fills up). Fetching the same file from a machine 'behind' the pfsense, I only get about 6KBps.

The pair fine (quickly) until i moved to BGP so something broke and its probably not hardwar…. I am at a loss as to where to even start looking, can anyone point me in the right direction? I have checked things like CPU/Memory and all seems ok.

Thanks
