I presume the comments about disk-based muds running faster than
memory-based ones are including the tacit assumption that one is talking
about muds that don't have the option of running on a machine with a
large surplus of RAM? I run a commercial project, and it seems the only
option for really optimal performance is to make sure you have enough
RAM to keep everything in memory that you need. I also don't do a bunch
of dynamic stuff - I prefer to do all mallocs and loading of maps and
objects at startup, and keep it there. I always believe malloc and free
are the devil's tools for fragmenting heaps and bloating memory usage,
if used during runtime rather than only at startup and shutdown.
Anyway, my server can currently handle over 150 people quite well with a
memory footprint of under 32 megabytes. I don't see any reason why I
should ever be experiencing a significant number of page faults. Disk
reads consist pretty much of just the character name/password file,
which I presume the OS has mostly in its cache most of the time.
Writing out logfile info, and maps when a builder uploads a new one,
both can generate some overhead. I was planning to set up a seperate
process that does all disk writes, and have the other processes dump
data to it and then go on about their business. But a friend of mine
told me about how they eliminated their disk-writing bottlenecks when
they purchased a RAID array for the server, which essentially does the
same caching of writes into RAM, only it's done for you, in hardware.
I realize that purchasing a RAID array isn't an option for most hobby
projects. Still, I would think that disk-based servers would be faster
for some muds, not for all muds. (Depending on memory footprint,
configuration of the machine in question, and whether it's running other
things besides the mud or not.)
