Guest Jondavisct Posted March 15, 2012 Posted March 15, 2012 We have a recruiting firm with 30 people that are utilizing their computers and Internet Explorer all day long. We have mostly Vista 32-bit machines, but also a Windows 7 32-bit machine and a Windows 7, 64-bit machine. We must use IE due to the specific Website that we use for most of our CRM process (bullhorn.com). Recently Microsoft forced the IE9 upgrade on most of our users and now we are experiencing slow downs in multiple sites: Bullhorn.com TheLadders.com ZoomInfo.com Monster.com What seems to happen is that everything is working great when you first start IE9 (Slightly faster than IE8 was), then over a period of time that ranges from 90 minutes to 4 hours, the system slows to a crawl. What we see is that CPU performance goes from 5-8% when IE is first opened to as much as 60% after the specific period. At 60%, IE9 is almost unusable. Closing and restarting IE9 immediately fixes the problem for the next 90 minutes to 4 hours. We have seen a correlation between the number tabs that are open with complex sites and how quickly the CPU slows down. This problem is happening both on the Vista 32-bit and the Windows 7 32-bit machines (Have no data on the Win7 64-bit computer). The Windows 7 32-bit machine is a 4-core processor and IE9 will slowly bring the first core to as much as 60% usage over a number of hours. We have updated Java, Flash as well as cleared the Internet Explorer cache, history and favorites to no avail. We have also disabled any add-ons that we can. I recently downgraded someone to IE8 and the problems went away entirely. That is not the ideal solution for our entire office since we have some Issues with IE8 and a click to dial add-on that many of our people use. IE9 solves the crashing problem with this add-on. But we have disabled the Click to Dial add-on in IE9 and we still see the slow down issues. I have also reviewed memory usage and the problem does not seem to be a Memory Leak. Memory usage seems to stay pretty consistent, leaving us about 28-35% of our 2GB of RAM free when everything is running. While speaking with the people at TheLadders.com, they stated that they have had this problem reported by a number of users that have recently gone to IE9 and they are recommending that all of their users go to a competitive product. That is not an option for us due to our primary product (Bullhorn.com) only working on IE. Continue reading... Quote
