PHP解释器如何工作？ [英] how does the PHP interpreter work?
问题描述
我注意到当我的博客软件试图联系时
www.weblogs.com ，要使用更新服务，我的整个网站（所有PHP）
减慢速度。联系 www.weblogs.com 可能需要很长时间。我不能确定发生了什么，除非PHP解释器陷入困境
试图联系 www.weblogs.com ，因此不太能够将PHP页面提供给其他网站访问者。但是如果PHP解释器很容易受到减速的影响，那么看起来PHP似乎无法扩展到处理大型网站的
，我知道它运行一些非常大的网站。
什么样的情况会降低PHP解释器的速度？

大部分时间瓶颈是数据库服务器，而不是
语言翻译。

同意Phil。您的日志文件可能很大，并且在访问它们时会遇到
问题。尽量减小尺寸。
DB是90％（或95％）时间的罪魁祸首。只需添加更多内存，缓存密钥，执行更好的结构（包括
模式的非规范化），优化表通常可以解决问题。

尝试通过Internet读取数据流。
I notice that when my weblog software tries to contact
www.weblogs.com, to use the update service, my whole site (all PHP)
slows down. Contacting www.weblogs.com can take a long time. I can''t
figure out what is going on, unless the PHP interpreter gets bogged
down trying to contact www.weblogs.com, and so is less able to serve
up PHP pages to other website visitors. But if the PHP interpreter was
that vulnerable to slow-downs, it doesn''t seem like PHP could scale to
handle large sites, and I know that it runs some very large sites.
What sort of situations can slow down the PHP interpreter?

Most of the time the bottleneck is the database server, not the
language interpreter.

Agree with Phil. Your log files are probably big, and you run into
problems accessing them. Try to reduce the size.
DB is the culprit 90% (or 95%) of the times. Simply adding more
memory, caching keys, doing a better structure (including
denormalization of schema), optimizing tables usually does the trick.
