Re: [Trinidad] Browser memory consumption

[Renzo Tomaselli]

Hi, I wonder about any way to influence browser memory across multiple requests (e.g. no PPR). Till now I was pretty sure that any browser resets *all* at each cycle, thus leaks shouldn't be possible at all without PPR. Or if any appears - that should due to a browser fault - without any chance to fix it from the application point of view. I use Trinidad since a long time and I never checked out memory usage according to the above thought - concentrating myself on potential PPR leaks. Am I wrong in assuming that ? -- Renzo Davide Bonicelli wrote: Hi Max,    thanks for your help.   I ran sIEve and pointed it the homepage of my application. It didn't detect any leak, but three cycle dependencies and an orphan. I cannot post the output of the scan because it's humongous! However, if I run "Auto-refresh" on my app for few seconds, I can see the memory usage increasing linearly with increments between 380Kb and 1500Kb per refresh. Meanwhile, the number of nodes used in the DOM never exceed 92.   At this point I suppose Trnidad is not leaking any memory, but somehow IE is not releasing memory while navigating through the pages of my app. I don't see this behaviour in IE if I "Auto-refresh" other websites (ex. google.com), where the memory used by IE is stable.   I also have to correct my previous post: a deeper analysis shows me that Firefox is deallocating the memory correctly while using my app (too bad my client wants to use IE7).   I don't know if this problem is worthed a deeper investigation.   Thanks Bye Davide   On Thu, Mar 27, 2008 at 9:53 AM, Max Starets <[EMAIL PROTECTED]> wrote: Hi Davide, If Trinidad's Javascipt library  leaks memory when user navigates from page to page, it is not normal or acceptable. There are tools, such as "drip" and "sIEve" that van help us diagnose the problem.
