It's a pity that squid cannot use mmap() to do file IO on the 4K chunks in it's memory pool (I can see that this is not a simple thing to do though, but that won't stop me wishing.

However, for these systems to boot successfully, the "mem" command-line argument has to be passed to Xen. For example, on a system with 128GB of memory the elilo.conf file should include the directive +The "xenheap_megabytes" hypervisor option is now supported on ia64 systems as well. coming again from previous questions on this, I've expanded the virtual machine a little bit in terms of a direct API to read and write data to the VM.. I've attempted to add a callback system so that host apps can add callable code that can be used by the scripts though I have no clue how to implement this. If you don't want it to be so large, reduce your cache_mem and object size limits for gopher, http and ftp in squid.conf.
