Windows 64位上的Apache 32位问题

Question

I have a Windows 7 Enterprice 64 bit and with 8GB RAM and I run a localhost with PHP, Apache and MySQL. However, Apache is (officially) still in 32-bit binary. And my system is performing at a enormously low speed... Is this a common problem or are there any tips or trics to boost my performance?

Answer 1

tl;dr version : It is not the 32-bit Apache that is slowing it down.

We would need more information to determine the cause of the problem but my guess is that it isn't the fact Apache is 32bit and Windows is 64bit.

The main difference between 32 and 64bit applications is that 64bit applications can access more memory directly (normally over about 3.5GB).

Apache itself is not particularly slow, it is all the modules you load with it (PHP, Python, mod_rewrite, etc).

It is most likely one (or more) of the following:

• High Requests/sec - you have a high number of requests per second
• High Processing Overhead - programs/scripts are using a lot of memory/CPU
• Poorly Written Programs/Scripts - programs/scripts are inefficient or leaking memory
• Other Processes - other programs on your PC (including Windows itself) may be using up your memory/CPU such as MySQL

Answer 2

Apache 64bit builds do not generally outperform the 32bit builds by more than 5%.

The only time I've seen a major slowdown running Apache on Windows was due to anti-virus software running.
