Hello,

We have a few servers connected to netapps via NFS for whisper storage, right now, usually when we reach a consistent 40.000+ metrics per cache, it fails to graph for a few hours, and then eventually flushes onto disk. 

We are using 2 instances per server (24 threads CPUs with 48GB of RAM), with the following config:

Do you see any way to make this faster? The system seems fairly IDLE so not a RAM/CPU issue in my view.

[cache]
MAX_CACHE_SIZE = inf
MAX_UPDATES_PER_SECOND = 3000
MAX_CREATES_PER_MINUTE = inf

LINE_RECEIVER_INTERFACE = 0.0.0.0
LINE_RECEIVER_PORT = 2003

PICKLE_RECEIVER_INTERFACE = 0.0.0.0
PICKLE_RECEIVER_PORT = 2004

CACHE_QUERY_INTERFACE = 0.0.0.0
CACHE_QUERY_PORT = 7002

LOG_UPDATES = False

WHISPER_AUTOFLUSH = False


Thanks for any answer you might have.

Cheers,
Steph
