I think you've been given bad advice here. I've seen a 700MB memory footprint on TWS too, but this is usually when I have more than 5 charts open and a lot of bars in them. Also, a lot of tickers and other windows open will spike the memory. In simple terms, TWS is a crappy piece of software, do not use it. Use a front-end with the Gateway or just open TWS to connect to it (I had problems with the Gateway much more often than with TWS).

Getting more memory is not a problem but on 32bit systems (and TWS afaik doesn't exist for 64bit) you will hit the memory limit at around 1.6GB per application. That can be as little as 20 charts open and 200 tickers. Also, TWS doesn't clean up after itself after closing charts. So, all in all, crappy software.

As for browser vs download version, I'm not sure what you mean but if you go to the main website > Trading Technology > Desktop Trading > Standalone Downloads > Windows Download > Install TWS , you will be taken to this link:
http://download2.interactivebrokers.com/download/tws40_install.exe

That installs it by default to C:\Jts. That is the downloaded, proper version, 99% people should use.

yes, exactly this is the way I have logged in for last 3 yrs. It didn't install anything on my system. That is what I meant.

The memory is now 445MB.

I never had this problem of TWS using excessive memory before. Other people who replied on this thread have confirmed this. I am using around 20 tickers and 1 chart, 1 T&S and 1 Market depth trader - I guess this is not overloading the TWS.

Also, I have seen memory usage by TWS increases with time. So, when I close and re-start TWS, memory usage is low but then it increases as hours go by.

Something is most likely wrong - some kind of memory leak or something else. My Java and TWS are uptodate.

This is what help -> About Trader Workstation on TWS says
