* I'm running it on hard drive F * UniServer is in F:\data\usr\UniServer, www is in F:\data\www * It can runs fine on mine too most of the time but sometimes load causes stability issues. This might also be conflict between Comodo Internet Security Premium and Apache.. either way disabling eAccelerator fixes it * Without IIS * Don't understand the question * I don't care about portability. I mean sure it is nice but in my eyes Uniform Server is secure version of portable WAMP packages. Security is most important, then comes portability and then optimizers like eAccelerator. * Uniserver XP is actually a good idea because these days it is starting to lose it's customer base and becomes more and more uncommon
