【问题描述】：
我对在 Digital Ocean 服务器上运行的 Magento 商店有疑问。
这是我的液滴配置：
2GB Ram | 40GB SSD Disk | New York 2 | Ubuntu Ubuntu 12.04.3 x64
当我使用 Magento 商店时，它可以正常工作，除非我尝试创建帐户或进行购买。
然后需要2分钟完成购买。
我在本地（使用 db）下载了整个网站，订购和创建帐户只需几秒钟。
我尝试将 droplet 升级到 4GB 内存，但还是一样。
这是我的 php 配置：
max_execution_time 30
max_file_uploads 20 20
max_input_nesting_level 64
max_input_time 60
max_input_vars 1000
memory_limit 512M
我不确定如何继续调试。有人可以建议吗？
更新 #2（基于 MageWorx 的 UPD）： 根据 MageWorx(updated) 的建议，我在服务器上运行了 mysqltunner。结果如下：
[OK] Logged in using credentials from debian maintenance account.
[OK] Currently running supported MySQL version 5.5.38-0ubuntu0.12.04.1

-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Variables to adjust:
query_cache_limit (> 4M, or use smaller result sets)
这些是 apachebuddy 的结果：
Your server has 2002 MB of memory
The largest apache process is using 39.78 MB of memory
The smallest apache process is using 15.04 MB of memory
The average apache process is using 17.32 MB of memory
Going by the average Apache process, Apache can potentially use 433.00 MB RAM (21.63 % of available RAM)
Going by the largest Apache process, Apache can potentially use 994.50 MB RAM (49.68 % of available RAM)
