Hi, I have been wondering how to judge what limits a certain machine can handle. When I install a new machine I always do some fine tuning. Like bumping up FD_SETSIZE to have more file handles. I add extra stuff to my kernel config to raise certain limits. A Example is something like this. options SOMAXCONN=2024 options NMBCLUSTERS=4096 options CHILD_MAX=1024 options OPEN_MAX=1024 options "MAXMEM=(256*1024)" options "MAXDSIZ=(256*1024*1024)" options "DFLDSIZ=(256*1024*1024)" options FD_SETSIZE=9096 My question is. How can I judge what a machine can handle as far as file handles or open childs. For example let say I have a, Pentium III 450mhz with 256ram. And scsi HD's. What can a machine like that handle? Is setting the FD_SETSIZE to 9096 asking for trouble? I know doing something like that to a low end machine might be. Now on the other hand I don't want to set these limits to low or I will start seeing out of file handle errors or out of mbuf's. But I don't want the machine to over run its limits either and crash.
