经过 ed036ef 这次优化,
4.8.0 对比 4.7.2 在 Log.DEBUG = true(开启日志)的情况下:

TestRecord[] 耗时降低至原来 73%,性能提升 27% 至原来 1.3 倍;
Moment[] 耗时降低至原来 80%,性能提升 20% 至原来 1.2 倍;
朋友圈列表耗时降低至原来 81%,性能提升 19% 至原来 1.2 倍。

其中每个数组都按 100 条来测试,如果每页数量更大或每项数据量更大,则提升会更加明显。

主要因为省掉了 AbstractObjectParser.onSQLExecute 878 行 for 循环 put 100 条数据(有日志) 3ms-8ms (MacBook Pro(13 英寸,2015 年初期)2.9 GHz Intel Core i5 16 GB 1867 MHz DDR3 MacOS 10.11.6 )
https://github.com/Tencent/APIJSON/blob/master/APIJSONORM/src/main/java/apijson/orm/AbstractObjectParser.java

以及 AbstractParser.onArrayParse 中用 1 次 addAll 替代 100 次 add 减少不必要的 ArrayList 频繁校验和扩容

腾讯 CSIG 某项目性能测试结果

1. 测试环境

1.1 机器配置

腾讯云tke docker pod, 4 核 / 16G。

1.2 db机器配置

腾讯云8核32000MB内存,805GB存储空间

1.3 测试表建表DML、数据量(mysql 5.7)

CREATE TABLE `t_xxxx_xxxx` (
    `x_id` bigint(11) unsigned NOT NULL AUTO_INCREMENT,
    `x_xxxx_id` int(11) unsigned NOT NULL DEFAULT '0' COMMENT 'xID',
    `x_xid` int(11) unsigned NOT NULL DEFAULT '0' COMMENT 'xxID',

  • 数据量:18558903

  • mysql版本:5.7

  • 数据分布:使用group by 统计,基于其中x_xid来group by,得到以下表格:

select x_xid, count(x_id) counter from t_xxxx_xxxx group by x_xid order by counter desc limit 10;

x_xid counter
xxxx36 696376
xxxx38 418576
xxxx63 384503
xxxx40 372080
xxxx41 301364
xxxx08 248243
xxxx46 223820
xxxx07 220234
xxxx44 207721
xxxx02 152795

1.4 日志打印设置

Log.DEBUG = false;

AbstractParser.IS_PRINT_REQUEST_STRING_LOG = false;
AbstractParser.IS_PRINT_REQUEST_ENDTIME_LOG = false;
AbstractParser.IS_PRINT_BIG_LOG = false;

2. 测试脚本 (使用Table[]: {Table: {}}格式)

脚本统计方式:

  • 基于linux time命令输出的realtime来统计。

  • 分2个场景测试:一个不带where条件、一个带x_xid in (xxxx36,xxxx38)的条件,该条件能匹配出100W+数据,方便覆盖10W-100W之间的任何数据量场景,这里事先用select x_xid, count(x_id) c from t_xxxx_xxxx group by x_xid order by c desc;这样的语句对表做了统计,x_xid=xxxx36有696376条记录,x_xid=xxxx38有418576条记录。

脚本:apitest.sh

#!/bin/bash

以之前的 APIJSON 4.6.0 连接 2.3KW 大表带条件查出 12W+ 数据来估计:
https://github.com/Tencent/APIJSON/releases/tag/4.6.0

---------- | ---------- | ---------- | ---------- | -------------
Total | Received | Time Total | Time Spent | Current Speed
72.5M | 72.5M | 0:00:05 | 0:00:05 | 20.0M

/get >> http请求结束:5624

4.6.0-4.7.2 都没有明显的性能优化,所以 4.7.0 只花了约 2s 应该是因为换了张表,平均每行数据量减少了约 65% 为原来的 35%。
APIJSON 4.6.0 查原来 2.3KW 大表中 100W 数据按新旧表数据量比例估计耗时 = 20.632s / 65% = 31.7s;
APIJSON 4.6.0 查原来 2.3KW 大表中 100W 数据按同表查出数据量比例估计耗时 = 100W*72.5M/(12-13W)/(20M/s) = 27.9s-30.2s。

两种方式估算结果基本一致,也可以按这个 35% 新旧表平均每行数据量比例估算排除网络耗时后的整个服务耗时:

APIJSON 4.6.0 查原来 2.3KW 大表中 12W+ 数据量服务耗时 = 总耗时 5.624s - 数据 72.5M/下载速度 20.0Mbps = 2.00s;
APIJSON 4.7.0 查现在 1.9KW 大表中 10W 数据量服务耗时 = 总耗时 1.928s - 数据 72.5M*35%(10/12)/(下载速度 10-20.0Mbps) = 0.00-0.87s;
APIJSON 4.8.0 查现在 1.9KW 大表中 10W 数据量服务耗时 = 总耗时 1.392s - 数据 72.5M*35%
(10/12)/(下载速度 10-20.0Mbps) = 0.00-0.33s,降低 62%;
APIJSON 4.7.0 查现在 1.9KW 大表中 100W 数据量服务耗时 = 总耗时 20.632s - 数据 725M*35%(10/12)/(下载速度 10-20.0Mbps) = 0.00-10.06s;
APIJSON 4.8.0 查现在 1.9KW 大表中 100W 数据量服务耗时 = 总耗时 16.481s - 数据 725M*35%
(10/12)/(下载速度 10-20.0Mbps) = 0.00-5.91s,降低 41%。
