Using redis-benchmark below:

redis-benchmark -n 10000 -t set,incr,get,lpush,lpop,lrange,mset -q

Config

redis: close save and aof

ssdb: close binlog manually below:

  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());
  }

leveldb：

  compression       = false
  block_size        = 32KB
  write_buffer_size = 64MB
  cache_size        = 500MB

Conclusion

ledisdb is little slower than redis or ssdb, some reasons may cause it:

go is fast, but not faster than c/c++
ledisdb uses cgo to call leveldb, a big cost.

However, ledisdb is still an alternative NoSQL in production for you.
