IB TWS - Freezing & Crashing

Interesting to see that your upload speed is so much faster than download speed.
In my case: ping 9 ms, download 9.6 Mbps, upload 9.85 Mbps.

Nevertheless, I don't think that your internet speed is your bottle neck. Are you sure that your computer has enough RAM available, and does not have to resort to using swap space on your hard drive? TWS is known to be rather memory-hungry.

Sorry, I got it backwards: 7mb download and 1.7mb upload. I have 8GB ram and the max TWS uses is about 1gb. No background apps while using TWS.

IB did recommend to try the Offline version of TWS. I'll give that a try when I have more time.

Could it be that TWS is not able to find and launch your web browser? There is a setting in TWS (but I don't remember where) where you can set the path to your browser on your PC.

Pretty sure that isn't the problem, as the issue only happens in situations where I am other-wise affected by the "slowness" problem.

But I gave it a shot anyway... I just went into the Global Configuration and set the browser path to:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"

Which is copied directly from my desktop shortcut.... and No dice, I get the same exact error dialog box in TWS when trying to go to Account Management Home.
 
I love the fact that we've all got our tweaks, that all stem from such a variety of experiences.
Different 'net delivery, different CPU protocol, different RAM/RAM-disk/etc configurations,... we still deal with different Java vintages, etc etc etc......

It tells me that I am not so alone, when I 3-6 times/day, click open TaskManager/ShowAllUsers or weekly (or more) hit speedtest.net, or watch the consumption and misbehavior when I have a 'net-ad-laden free-streaming CNBC doing the RAM-amoeba thing....... or when I just give up, and twice save my working TWS via Settings and SaveSettingsAs and all that......

Sound familiar?

I guess, we can take nothing as granted, and work in redundancies and operations-barometers wherever we can.

I guess it's just good to see it happening all around the world, and not just in my little wood-paneled palantir nest.......
 
Yeah, my work-around for using it in the office is, using TWS in a vmware virtual machine that is connected to my home network via a VPN.
 
I tried the Offline TWS (964.1e). The time from launch to the login screen is only 4 secs now (previously 11-12 secs) but the time from the Login button to a fully populated TWS is not much better at 38 secs. Doesn't matter if I deselect "Use/store settings on server". Also as I launch TWS, I'm looking at the Task Mgr/ Networking tab and the TWS bandwidth used does not come close to my max throughput. Once TWS is loaded, it takes very little bandwidth.

In TWS, when I click on the Account menu / Account Management page, it takes about 8-10 secs for the browser to begin to launch and 2 secs latter, it displays the account management page..
 
I installed TWS 960.2g which is available on the NinjaTrader website and the load times are fast and as good as I remember them being. But of course, it's an older GUI with many minor features missing.
 
Just had a fatal abort while using the new note taking system . Hard crash.

Hope you're up&running this morning, SOES.
FWIW, I'm running the stable/daily download (963.3e), and memory consumption is down/level (no creeping-crud RAM consumption), and interaction with other items (especially the Java-based items that sometimes are not so friendly, e.g., Firefox and OpenOffice) has been similarly stable, and even *cool-runnin'*, for the past week.
 
I have TWS "stable" build 963.3m installed on my macOS 64bit with 32GB memory, and configured heap space -Xmx8G in ~/Jts/tws.vmoptions, but TWS still keeps freezing, especially when opening some charts in the volatility lab for SPX; it is basically unusable for me.

Can someone recommend a recent but usable version prior to 963.3m?
