If we compile a kernel (2.4.0 or 2.4.2 up to ac25) that uses all 16 GByte RAM the machine gets very slow. For example network Bandwidth of 100MBit Ethernet is about 1-50kByte/sec. Access to harddrives seems to be equally slow. I really do not know where to start looking, but I know that lots of people seem to be using n-way Xeon with 16+GByte RAM without severe performance problem. KEYWORDS: kernel, slow, maxdata, 16GB KERNEL: 2.4.0 and 2.4.2 (upto ac25) If more information --- like /proc/cpuinfo or uname -a or versions of installed software ... --- is needed to analyse the problem, please tell me, I will gladly send it.
