So I don't think it was well tested under various workloads. But if you can provide more information for the issue I think it could be enhanced in near future. > Is better to buy another Intel card and going on using em0 driver ? Remember, all hardwares supported by age(4) are for consumer motherboards. Even if L1 has much better performance/design than that of its successor, L1E, it's still not for server market. The same is true for em(4). Since there are too many variants you may have to choose the best hardware model that is suited for your workload. > Any other problems affecting this release just now ? > > And, last question, 7.1-PRERELEASE should belong to the STABLE tree ? > In that case why during the last two months is so instable for > production enviroment ? > > Maybe I'm wrong, so I accept suggestions. -- Regards, Pyun YongHyeon
