=?iso-8859-1?Q?Luis_Concepci=F3n?= | Hi!
I'm using DBISAM 4 (latest release). I have been reading about MaxTableDataBufferSize, ...BufferCount, ....IndexBufferSize, etc... properties, but I still have some doubts regarding this. I 'undesrtand' that those properties don't affect C/S connections, but only local tables or file-sharing networks? Nowadays, 90% of our customers have 1GB-2GB RAM, so I think I could use these properties to improve our app speed. Our app can be executed in C/S mode (lan or internet) and in file-sharing mode, depending on customer decision (and money So... 1) Do these properties improve C/S LAN speed (one server, several clients)? 2) Do these properties improve C/S INTERNET speed (one remote server, several remote clients)? 3) Do these properties improve local files speed (only one computer)? 4) Do these properties improve shared-files network speed (one shared server, several network clients)? There are about 15 tables, with indexes. Some tables (only 3 or 4) have blob field (only one per table). In C/S mode, the speed is perfect, but in file-sharing mode (two or more computers) it usually takes about 1 minute to search, locate, filter, etc... with some tables. Is it possible to improve it? Thanks a lot! I know this have been discussed a lot, but actually I don't understand it. Maybe because of my poor english (I'm from Spain) |

=?iso-8859-1?Q?Luis_Concepci=F3n?= | Hi, Tim...
Is it enough to change the global 'Engine' session 'Max...........Size' properties or should I do something else? I change them before opening the sessions, but I have been testing and I can't see any speed improovement. When/Where do these properties make effect?

However, you may need to increase them quite a bit before you see any improvement, and there is always the possibility that your particular situation will not be helped by increasing them due to other factors. -- Tim Young Elevate Software www.elevatesoft.com |
