Looks like we are going to purchase this tool. One of the options is to "capture login information". The datasheet says this is done by Profiler APIs and stored in a table. Our query is - will this have a noticeable effect on performance? Have any other Tippers any opinions? If you use this, how many connections do you have? TOur server can have up to about 2500 connections at any time, though not all active. We had a problem using Profiler, but to capture and display, whereas this is only to capture and save. Thanks.
