Agreed, in spades! There was a software solutions company that had been telling their clients to remove any AntiVirus apps as they slowed down their Firebird/IE based app something fierce. When they installed their app at one of my client locations, with a much larger database than their other clients, their app was extremely slow. They made their initial mistake with me by casting claims of a defective network simply because we were using 100vg (vg = Voice Grade, which they said was inferior technology. VG means ethernet can run on Cat3 and still provide reliable signals, it screams on Cat5 or higher. They sure boned their credibility on that.). Once I proved, using their performance criteria as stated in advance of the test, the network was fast and reliable they next blamed Symantec AntiVirus. Sure enough, turning it off helped a tiny bit, but not a lot. I had already disabled scanning network drives long before. Turns out they cache the ENTIRE set of tables from the Firebird Server to the local PCs when they first load their app. Why? To enhance performance at the desktop level, of course!. I still recall the look on the face of their lead designer when I asked if he was caching all tables locally - he knew he was dead meat. For most of their clients the AV apps were scanning all files from the network, and some of the files were fairly big. Well, certainly the AV had to be the problem, not the few hundred Mg of records coming over, whether they are needed or not! In my client's case the files were so huge the SAV impact would have had very little adverse impact anyway. Ed once told me that even a good database can be ruined with shitty software design. Case in point, eh? But, still they felt we had to uninstall SAV, and run no protection on any PCs or Servers, despite my having proven the SAV was not impacting their application's performance in any practical manner (200+ PCs on the LAN at the time). When I said we would toss their app out first, as Federal law now requires businesses to take reasonable measures to prevent systems from being compromised along with private consumer data, they redesigned their app to not cache the largest tables locally, and ended up with a less terrible app - still slow, but they popped in a larger Server to "fix" that. It did no good. Good job, Idiots.
