SolarWinds' interface is slow, and this is a global concern. Every SolarWinds user complains about the sluggishness. The response is slow. If you browse from one page to another, you have to wait. Our company is a massive user with plenty of licenses, so the performance issues could be due to the load per license. Ten thousand components can be mapped under one license. So SolarWinds needs to take care of the speed problem. It cannot be this slow. That is a huge complaint. Otherwise, the tool is good. It should also be easier to upgrade SolarWinds. AppDynamics is harder to deploy but easier to upgrade. So AppDynamics takes a lot of time and effort to install, but you can upgrade it in minutes. SolarWinds is the opposite. It's easy to deploy, but upgrades take forever. To date, nobody can complete it on time, so the production environment is sitting idle. The upgrade time matters because you only install the solution once, but you'll need to upgrade the solution repeatedly over the life of the product. A complex installation isn't an issue, but I mind if the upgrade takes too long because it's already in production.
