It won't improve the speed per se, but it will stop the slowness and loss of http response caused by reaching your heap size maximum allowance. It will also free you up from having to watch it so closely and keep you from having to interrupt your client's service while you restart jrun.exe. It will also buy you some time to examine your code and monitor your apps to identify possible bottlenecks without having to continue the restart pattern you are currently experiencing. Even moving it up to 768mb should yield a significant improvement.

Yeah, we are planning to use Fusion Reactor to monitor our apps. In our case, its client variables used throughout i.e. no session variables at all. I will definitely monitor pages that are running slow to see what is going on but knowing hardware setup is also important. So I was just trying to get an idea of what others are doing. Coming to heap size, i think ours is set at default 512, if I am right. I will have to convince my team to up it to 1024mb. Does it improve performance significantly? Just curious.

That should alleviate most, if not all, of the slowness. On that note, one thing I've run into is that the session scope can become quite obtrusive under load. Sites that carry a lot of session information with high traffic will eat up your memory pretty quickly. Maybe some code examination may be in order as well.

Judging by what you say here, there may be some other issue going on besides what jrun.exe is using. But, if you're not having memory issues and you've got it to spare, I'd say go ahead and bump it up. BTW, what version of CF?

About 20 sites and high traffic site. I am not sure how many users though. I guess there is a limit of 4gb memory on 32 bit systems. I noticed lsass.exe is taking 600,000K of memory and jrun.exe is taking 193,604K of memory. So lsass.exe is using thrice as much. Any suggestions? <Ajas Mohammed /> http://ajashadi.blogspot.com We cannot become what we need to be, remaining what we are. No matter what, find a way. Because thats what winners do.

I'd be interested to know how many sites, what kind of traffic each site brings, that kind of thing. But, if I had 4gb of memory, I'd set my heap size to 1024mb. That is good enough usually unless you have a relatively high-load server environment.

Hi, I was wondering what is the ideal memory you prefer on an CF Production server? We are running Intel Xeon CPU E 5450 @ 3.00 GHZ, 4GB RAM. Any suggestions as far as If 4gb memory is good enough or it should be greater than that for a production server?
