Speed: Remote Mode vs Local Mode. |
Wed, Jul 26 2017 8:55 PM | Permanent Link |
Steve Gill | I have always used EDB in Remote mode (connecting to the server application). I have never tried Local mode (connecting directly to the database).
If there is anyone who has tried both, have you noticed any general speed difference between the two? I would think Remote mode would be faster, especially with a lot of users, but that's just an assumption. Just curious. = Steve |

So much depends on just what you're doing and the environment you're doing it in. My findings were that generally, single user case, c/s was faster than f/s but there were some operations that were faster in f/s. I built a test bed (thrown away now) to try and compare for my circumstances. Things that will have some influence (not how carefully I've phrased that) - chattiness of the application - number of users - speed of LAN - loading of LAN - number of queries - number of filters - duration of queries - ratio of batch processing - power of the server - local vs server processing That starter list will give you an idea why its better to build your own testbed Roy |

Meaning, doing batch processing (while (not EOF) do...Next) from the client and other types of operations that end up being very chatty. In such cases the answer is always to move that functionality into the EDB Server in the form of a procedure/function (native or SQL). Tim Young Elevate Software www.elevatesoft.com |
