Operations per second hit a hard limit
Hello, I am testing couchbase 1.8.1 on a single server using C++ library libcouchbase on ECLIPSE platform Version 3.6.1 and I seem to reach a hard limit on the number of operations per second (at around 70K).
CPU usage and IO are very low while hitting the limit so I'm wondering if there is something I am missing, like if I could change or adjust some parameters (maybe in a config file) to stop this from happenning.
Some benchmarks done by CISCO claim up to 250K operations per second for a single server (http://blog.couchbase.com/understanding-performance-benchmark-published-...).
I have tried both with and without the following command
CENTOS Release 6.2(Final)
Kernel Linux 2.6.32-220.el6.x86_64
64 X AMD Opteron(TM) Processor 6274
RAM: 252.3 GiB
Cluster: Total: 225 GB
Bucket 1: 135GB/185GB Item count: 1386592706
Bucket 2: 24.4GB/34.5GB Item count: 113751337
Thanks in advance
