Currently, my task manager is showing 717 MB memory being used by TWS. It is also using 17-20 CPU. I remember earlier it used to be much less like close to 300MB or so. My task manager shows: javaw.exe 717544 K Memory My TWS has become slow, when I want to modify an order price or number of contracts, it takes a little bit of time before it responds. Anyone else facing similar issues? Please post how much memory your TWS is taking.
