MyDAC WAN performance
MyDAC WAN performance
Hi, we are developing MyDAC software for local area networks How would the performance of this software be effected at WAN? Do you think that we could have unexpected problems? (The software is related with document management, sometimes with huge amount of data)
I'm using successfully myDac over WAN (DSL lines). You need to take in care a few things to make it work well, query the least amount of data (Make querys return the minimum fields and rows needed), and set the connection to use compression.
With blob's of coure it takes its time, just like you're downloading the file. My trick is create a master-detail, in detail i select blob's, and then displaying a grid for example is fast, and when user moves, the blob is loaded on demand.
Also change the max_allowed_packet to be bigger, otherwise you'll have problems with big blobs ( both on LAN and WAN!).
Regards
