Do you think this may be the EXT2 issue? Still when swap starts working there is a slowdown to the whole system. What are recommended flags to build the kernel for efficiency? Does debug symbols in kernel can slow things down? Any hints welcome! :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
