GitHub user Cczzzz edited a discussion: 打印   Flush data to disk costs  代表什么

[NOTIFYME]putMessage in lock cost time(ms)=819, bodyLength=3268 
AppendMessageResult=AppendMessageResult{status=PUT_OK, 
wroteOffset=48701189672425, wroteBytes=3504, msgId='null', 
storeTimestamp=1724011632172, logicsOffset=68013587, pagecacheRT=819, msgNum=1}

服务端偶现卡顿，打印上面的log ，大部分情况卡顿时也会出现  Flush data to disk costs  

版本 4.9.4 磁盘 aws gp3 3000 io/s

我发现里面是调用 MappedByteBuffer#force , force 卡顿时put 写入buffer 是否会堵塞导致这个问题？
