场景是 12k 写入 12 k 消费
16 c 32 g,ssd,rocketmq 版本 4.9.1
Scenario is 12k writes 12k consumes
16c 32g, ssd, rocketmq version 4.9.1
如图片所示,我添加了一些指标采集
As shown in the figure, I added some indicators
putBufferRt 方法对应指标 buffer 单位是微秒。
putBufferRt is buffer in Metrics,is μs.
有时候会大于2ms 呢,
Sometimes greater than 2ms.
如果用Arthas 去开的话
with Arthas
这个语句
watch *.DefaultMmapFile appendMessage '{params, returnObj}' '#cost>1'
大于2ms 的也挺多的
I don't know what's causing it, maybe it's a page fault in memory?
会是内存缺页引起的吗

changed the title
appendMessage poor performance
appendMessage poor performance 写入MappedByteBuffer 性能并不友好
