Memcached质量设置/添加卡住问题

我正在尝试使用bash/php对memcached服务器v 1.4.13进行大量设置/添加操作。它开始正常，但达到~1000项(~200KB)，我看到脚本操作继续，而memcached项的数量仍然保持~1000!我使用memcache-top和我自己的脚本来测量memcached项计数。

所有的键/值在输入文件中是唯一的。我已经尝试在添加/设置之间添加延迟，但它仍然没有帮助!

服务器标记:/usr/bin/memcached -v -m 2048 -p 11211 -u memcache -c 16384

我的问题是:1. 我做错了什么?2. 如何将所有数据从file导入到memcached?

卡住时的状态输出:
