## 测试环境搭建
|
||
|
||
+ Darwin karamatoMacBook-Air.local 13.1.0 Darwin Kernel Version 13.1.0: Thu Jan 16 19:40:37 PST 2014; root:xnu-2422.90.20~2/RELEASE_X86_64 x86_64
|
||
+ 2 CPU Intel Core i5 1.7GHz
|
||
+ 4GB
|
||
+ SSD 120G
|
||
|
||
使用redis-benchmark命令进行压力测试，测试语句
|
||
|
||
redis-benchmark -n 10000 -t set,incr,get,lpush,lpop,lrange,mset -q
|
||
|
||
redis只用内存模式，关闭持久化
|
||
ssdb使用默认的配置，手动更改代码关闭了binlog的功能：
|
||
|
||
void BinlogQueue::add_log(char type, char cmd, const leveldb::Slice &key){
|
||
tran_seq ++;
|
||
//Binlog log(tran_seq, type, cmd, key);
|
||
//batch.Put(encode_seq_key(tran_seq), log.repr());
|
||
}
|
||
|
||
ledisdb使用跟ssdb相同的leveldb配置
|
||
|
||
leveldb配置：
|
||
|
||
compression = false
|
||
block_size = 32KB
|
||
write_buffer_size = 64MB
|
||
cache_size = 500MB
|
||
|

可以看到，ledisdb的性能比redis以及ssdb略差，（至于为啥ssdb lrange性能这样差我感到比较困惑），但还不至于不可用，我觉得可能如下原因：
|
||
|
||
+ go语言自身没有c，c++快
|
||
+ ledisdb使用的cgo调用的leveldb相关函数，这块开销其实蛮大的，后续是优化重点。
