FAQ only explains -how- to increase the limit, not what the impact is. Or perhaps I've missed a section.... The need is dependant on how heavily your proxy will be used. I'd go for an initial filedesc limit of 4096, monitor the usage, and increase if you get 'out of descriptors' errors. I have a Linux machine here with a filedesc limit of 16384, and I don't notice a performance degradation. Joost
