rdb test procedure

1. Modify redis.conf profile

1. Open rdb (test aof, commented rdb, and restart redis)

# save ""
save 900 1
save 300 10
save 60 10000
注入数据

#默认开启数据压缩

rdbcompression yes

2. Close aof

appendonly no

2. Write data

#!/bin/bash
for ((i=0;i<100000;i++))
do
echo -en "helloworld" | redis-cli -x set name$i >>redis.log
done

3. The data is written using a script, and calculates the injection completion time

The amount of data	rdb time	rdb file size
50000	76s	1.1M
100000	197s	2.1m
150000	235s	3.1m
200000	305s	4.3M

The amount of data	aof time	aof file size
50000	79s	2.2M
100000	156s	6.5M
150000	234s	6.6M
200000	306s	8k8n
