How to check memory leak or memory usage of Javascript

[ericazhangjun]

Hi,

I am new for Javascript. I found my webpage is becoming slower and slower. I want to know how to check memory leak or memory usage of Javascript.

Thanks,

Jun

A quick search on Google for "memory leak javascript" shows at least 3 good tutorials in the first 5 results on how to avoid and/or detect these.

I mean if there is some tool to help me check memory leak dynamically, while I running the script.

I have found one on firefox.

Assuming you want one for IE (you don't say), try this:

http://ajaxian.com/archives/screencast-on-diagnosing-memory-leaks-in-ie

http://www.webstandards.org/2005/12/06/tool-for-tracking-ie-memory-leaks/

These were found in the first 10 results for a Google search on "memory leak tool".

Hope this helps,
Dan

I am using firefox, because I have to use greasemoney.

Could you recommend some tools used on firefox ?

Thanks,

Jun

You said you'd found one, so I assumed you wanted tools for another browser. Perhaps if you'd given clear requirements to start with?

You'd now not said which tool you've found for Firefox, so hopefully this isn't duplicating your findings:

If it is, perhaps you could start giving us some better information.

Or better yet, you could save Dan some time and just google it yourself.

Hi Dan,

Thanks a lot. Yes. I am using Leak Monitor to check if there is memory leak. However, I found it not be able to work on Solaris x86. After I deploy an environment on Linux. Firefox always crashes. Also it could not find memory leak caused by greasemonkey script. I do not know why.
