对单实例3.5.5版本进行压测时，cpu占用率很高，磁盘利用率很低

[guozhihao-224]

Is this a regression?

Yes

Description

• 机器配置：
  • Silver4316*2（20c * 2）
  • SSD_1.92TB*8[U.2_2.5_]
  • DDR4_32G*8[3200MT/s]
• pika配置文件：pika.txt
• 压测命令：./../memtier_benchmark -p 9221 --command="set __key__ __val__" --random-data --data-size=512 --key-minimum=1 --key-maximum=2000000 --threads=16 --requests=500000 --print-percentiles 90,99,99.9,99.99 --command-key-pattern=G --hdr-file-prefix=set_16_8 --clients=8

在进行压测时，发现cpu占用率特别高、磁盘利用率很低 1%不到，是否是我压测数据或配置参数的问题

需要查看rocksdb的日志，检查是否有出现write stall或者stop。
还可以调整的参数：
rate-limiter-bandwidth调大。
增加level0-slow-down和stop的 trigger阈值。
增大memtable 大小，增加immutable memtable个数。
这些对于写场景应该是有提升的。

You need to check the rocksdb log to check whether there is a write stall or stop.
Parameters that can also be adjusted:
rate-limiter-bandwidth is increased.
Increase the trigger thresholds for level0-slow-down and stop.
Increase the size of the memtable and increase the number of immutable memtables.
These should improve the writing scenarios.
