For instance, on a high end AS/400 or 3090 using DB/2 with a hashed index, repeated requests will get cached. So if you are hitting the same tablebase file over and over, it will speed up. They have spent literally millions of dollars figuring out how to make it as fast as possible. Now, it is probably possible to do it faster with some proprietary format. But a general solution means that you can get the data with general tools. It might be interesting to create a server that anyone can query as an ordinary service like a timeserver or DNS host or something. >Of course custom database formats have disadvantages (extra development time, >lack of compatiblity with standard query tools etc) but they can definitely go >faster and/or use less space. I have seen this said many times, and then seen the proprietary solution get knocked on their butt by a landslide. Now, I have no idea whatsovever if this would be the case. But I would bench it before I would believe it. I guess I must have some Missouri roots.
