No one has said it yet but you can disable TWS features. Make sure you're using only the ones you need.
Not sure. I stick with defaults - Unlimited and None, and that works well, together with regular JRE cache and browser cache clearing. One thing you could check is the size of that entire ...\cache folder shown in the "Location" box on the Temp Files Settings screen. For example, Right-click - Properties in Windows Explorer. Mine is under 10 MB, on each of 2 trading PCs.
thanks for suggestion. Id've done most of them and also found a newer build..1.5 version 8. reloaded that and restarted tws. now 70MB memory usage. Much better. I'll ck back here tomorrow for an update during the full mkt hours.
Check the command line (-Xmx256M). TWS is set up to allow the heap to grow to 256M. If this is optimal or just the choice of a lazy programmer is another question for another thread.
I'm using the standalone version, and when it starts it uses maybe 50 meg, that quickly grows to 100 meg, After an hour or two , it uses 200 meg. This is without any charts running. Someting is eating up all this memory. I run Excel and Quotetracker which both access the api, maybe thats the issue.
There has to be a memory leak. I gave it an extra 40 meg (set max memory to 200 meg) and by the end of the day it uses all of that up and starts to lock up.
well, i have the same problems [again]...after a couple of hours platform just slows down so much to make any tradin' impossible...have to re-boot at least a couple of times per session and when i do log-in again it takes ages to get it up and runnin'.
