Check out Larry Youngren's COMMON presentations on this subject. I think Larry holds part of the patent on the product. They figured out a way to do fewer disk accesses, as I recall, as well as fewer network transmissions in High Availability. If that recollection is correct, it'll go faster even if it isn't remoted.

We do not have this product. We do not do High Availability but we do journal every table and have full audit journaling on. Would this still help performance?

I've moved. I wasn't that impressed. But, it may be because I found a much bigger payback. Are you journalling? If so, do you have Resource

Adding this made a phenomenally huge difference. Comes with usual 70 day key to try it out. Which, if you line up the install just right will cover two month ends to test it.

Has anyone moved to using SSD drives and if so have you seen any significant performance improvement by doing so? We are not in need of additional space (running about 50%) and disk utilization (% busy) is not extremely high (10-15%). Wondering if a plan to migrate to SSD would be worthwhile.
