实时服务器上的FPDF性能比localhost差

标签: mysql performance memory-leaks lamp fpdf

我在下面使用以下php脚本,使用WAMP从20个类别中读取大约2300个带有图像等的产品;问题是创建一个213页的pdf需要3分钟;基于代码有一种提高性能的方法。我已经实现了这些更改:

在php.ini中

查找

post_max_size = 8M
upload_max_filesize = 2M
max_execution_time = 30
max_input_time = 60
memory_limit = 8M

更改为:

post_max_size = 750M
upload_max_filesize = 750M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M

并将其添加到C:\ wamp \ bin \ mysql \ mysql5.0.45 \ my.ini:

max_allowed_packet = 200M

这已经停止了我得到的outOfMemory异常&当我在我的VPS云服务器上使用相同的设置运行它时,它可以超过10分钟!请问有什么帮助吗?(我知道这是一个很大的脚本文件)(每页还有12个产品的业务规则,4行乘3)
