背景:現(xiàn)在的數(shù)據(jù)已經(jīng)寫到了redis隊列里面，完成了入棧的操作，后期打算從redis獲取數(shù)據(jù)，完成出棧的操作，出棧后然后做一系列的邏輯處理

????? 環(huán)境: VMware虛擬機? 內(nèi)存:1G?? 硬盤:60G? php環(huán)境:PHP Version 5.6.31? php框架:TP

????? 測試:事先在redis里面插入了30W條數(shù)據(jù)，分別模擬php單進程和多進程(3個多進程)

php單進程代碼:

public function sinsert() {
??????? //$redis = new Redis(); ?
??????? //$redis->connect('127.0.0.1', 6379);
??????? //寫到list類型緩存里面
??????? //lpush('zc_hk_list', serialize($zc_hk))
??????? //$accountRepayModel = D('AccountRepay');
??????? $this->repay->start();
??????? for($i=1;$i<=300000;$i++) {
????????? $arr = array("k"=>$i,"v"=>"dan".$i);
????????? //var_dump($arr);//exit;??????? ?
??????????? $this->redis->lpush('hongniu', serialize($arr));
??????? }
??????? $this->repay->stop();
??????? $spent_time = $this->repay->spent($echo=true, '全量寫入redis數(shù)據(jù)發(fā)送腳本');
??????? $this->repay->clear();
??????? /*$key = 'name';
??????? $value = $redis->get($key);
??????? var_dump($value);*/

??????? $list_len? = $this->redis->llen('hongniu');
??????? Log::write('單進程一共有:'.$list_len."條");

測試結(jié)果如下所示:

總結(jié)：因為redis是單進程單線程的，在只有一個redis實例的情況下，不管開啟多少個進程，讀取速度不會變快!

所以想要讀取速度加快可以開啟多個redis實例，寫入的時候?qū)懭氲蕉鄠€redis實例中，讀取的時候也是從多個redis實例讀取。
