So I had left TweetDeck application up on my desktop overnight and found my system sluggish and unresponsive in the morning.  I found there were 2 tweetdeck processes running each consuming 50% of the CPU and over 300mb RAM being utilized by the processes.  The application was unresponsive and didn’t even show up as a window, I had to kill the processes and restart the application.  I have noticed that the longer tweetdeck runs this problem seems to occur after 3 or more hours.  So I frequently shut down tweetdeck if I will be away from my computer for a few hours and re-open it when I return.

Google Chrome is another memory hog, I left Chrome open with about 30 tabs open at once.  The total memory consumption was about 200mb when I added all the chrome.exe processes together, but after leaving the windows and coming back 5 hours later, I saw the memory utilization was magically at 800mb for all same processes (no changes in the application at all, just leaving it all open for 5 hours and so much more memory was consumed).  It became so sluggish I couldn’t even click on any tabs, the browser just was frozen and reacted horribly.  I had no choice but to kill it and restart Chrome.

I noticed Chrome usually has 1 big process (most memory usage) and many little ones, if you kill the big process, it will automatically kill all child processes saving you from having to manually click and terminate 15-20 processes called Chrome.exe.

Just some observations of the past day on my system and applications consuming memory, more and more I am seeing applications have a horrible memory utilization, they don’t clean up memory after consuming it.  I had a game called Heroes of Might and Magic IV which would do the same thing, Heroes.exe would consume 100mb per hour, every hour I left the game up the process would be 100mb larger, until it could be 900mb in size if I left the game running overnight.

Beware for application memory utilization, many applications are not coded properly, it is beneficial to close out of applications when you are done with them instead of leaving them open for hours at a time, Firefox, Thunderbird, Chrome, TweetDeck and many others all consume greater amounts of memory the longer the applications stay open and are running.  If you have slower system performance or notice your mouse moving sluggishly, windows tabbing slower, switching between applications becoming delayed, these are all signs that your CPU or memory may be too heavily consumed, go into your task manager and terminate what could be your offending applications.
