Please don't take this wrong - but I'm going to laugh right now because how long have I been complaining about this VERY ISSUE and gotten no results?
Same here, friend, same here. Slow as a one-legged turtle. And YES, of course, I HAVE applied ALL of the so-called fixes and tuning and YES, I run the very latest, and YES, it was clean-installed on brand new VMWare servers (2008 R2) this last time, so it's not an upgrade over 10 other upgrades, and no, NO difference, it's still slow as that turtle I mentioned.
It can take several seconds to just move from one tab to another, a VERY long time to move from displaying one group of computers to another.
And no, the WEB-based console really isn't any faster, and worse, it's got some serious issues of it's own, making it nearly unusable at the resolutions we run here, as well as constantly resetting the page it's on if you so much as move the browser a single pixel.
SEP is great, but the console architecture is, well, pretty slow and cumbersome and the web-based is a huge disappointment to me.
To make it even usable, I run it on TWO computers so I can click someone on one, while it takes time to load, I can view or get something started on the other. Need to get to something quickly? Don't count on it.
In short, I agree 100%, it's very slow.
