php–DigitalOcean服务器上的Magento

我在Digital Ocean服务器上运行的Magento商店有问题.

这是我的Droplet配置：

2GB Ram | 40GB SSD Disk | New York 2 | Ubuntu Ubuntu 12.04.3 x64


当我使用Magento商店时,它正常工作,除非我尝试创建帐户或进行购买.

然后完成购买需要2分钟.

我在本地下载了整个站点(使用db),订单和创建帐户只需几秒钟.

我尝试将Droplet升级到4GB Ram,但仍然相同.

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


我不知道如何继续调试这个.有人可以建议吗？

更新#2(基于MageWorx的UPD)：
基于MageWorx(更新)的建议,我在服务器上运行了mysqltunner.这些是结果：

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：

解决方法:

我敢于认为问题是由缺乏mysql设置优化引起的.关键是没有优化mysql,你将无法提高网站速度,因为mysql不会使用100％的服务器资源.

这些是2Gb droplet的基本设置(/etc/mysql/my.cnf)：

key_buffer=32M
query_cache_type=1
query_cache_limit=1M
query_cache_size=32M
table_cache=128
innodb_buffer_pool_size=256M


由于这些是基本设置,您可以使用应用程序http://mysqltuner.com/进行进一步的mysql优化.
