Internet Explorer Static File Caching Defect
In going through cases we have with some customers, we’ve seen a few instances where Internet Explorer does not cache shared static resources. Within Load Tester, this problem becomes immediately apparent:

Memory consumption and reclamation – Chrome vs. Firefox
I reboot my laptop as infrequently as possible – which means that I keep Firefox running for weeks without restarting. At least, I would prefer to. But the longer it runs, the more memory it gobbles. The only way to reclaim it is to restart.
So when I read about the tab-isolation feature in Googles new Chrome browser which uses a separate process for each tab, it peaked my interest. I installed Chrome and tried a very quick (and not very scientific) test, as described below.
Firefox had been open for a few days and currently had 8 tabs open. I am … Continue reading »
