我在几台不同的机器上运行Apache qpid附带的qpid-bench工具来测试性能。我没有找到关于qpid-bench程序输出/结果的任何文档。以下是一个示例测试的结果:
$ qpid-bench
broker = localhost
port = 5672
count = 1000000
window = 100000
sample = 100000
size = 1024
mode = BOTH
timestamp = false
message_id = false
message_cache = false
persistent = false
jms_publish = false
jms_consume = false
help = false

我猜NP是发布的数量，NC是每个窗口消耗的数量。第一个数字是发送/接收的消息数。第二个和第三个数字是什么意思?
这是QpidBench.java的源代码:https://svn.apache.org/repos/asf/qpid/trunk/qpid/java/tools/src/main/java/org/apache/qpid/tools/QpidBench.java
下面是qpid-bench命令的选项:
$ qpid-bench --help
qpid-bench <options>
-b, --broker (localhost) the broker hostname
-p, --port (5672) the broker port
-c, --count (1000000) the number of messages to send/receive, 0 means no limit
-w, --window (100000) the number of messages to send before blocking, 0 disables
--sample (100000) print stats after this many messages, 0 disables
-i, --interval (100000) sets both --window and --sample
-s, --size (1024) the message size
-m, --mode (BOTH) one of publish, consume, or both
--timestamp (false) set timestamps on each message if true
--mesage-id (false) set the message-id on each message if true
--message-cache (false) reuse the same message for each send if true
--persistent (false) set the delivery-mode to persistent if true
--jms-publish (false) use the jms client for publish
--jms-consume (false) use the jms client for consume
--jms (false) sets both --jms-publish and --jms-consume
-h, --help prints this message
在QPidBench.java中由"double cumulative = 1000 * (double) count/(double) (time - start);"定义的第一个累积数。即在每个样本期内出版或消费的总数量。
第二个数字间隔由"double interval = 1000 * ((double) opts"定义。sample/(double) (time - lastTime));即在每个样本期内出版或消费的数量。
count是发布/使用的消息数和选项数。Sample是运行qpid-bench时在选项中定义的样本大小。
