Esteban, a analog 28.8 modem theoretically runs at 2,880 bytes per second. Actually throughput is probably half that - about 1,400 bytes per second. So that's fine for 250 bytes per second.
I think when you first start QCharts, there will be a spike in data volume as it loads up the charts and quote sheets with data. That is where you will probably notice a difference with a much faster modem, ISDN, DSL or cable modem. But I think that only lasts for a minute or so. After that, it should be less of an issue.
CPU speed will probably have an effect, but graphics speed will probably have a major effect also. You are pushing a log of graphical images around on the screen. Memory, I'm not sure of. In general, the more memory, the better. WinNT is a memory hog. Win98 also likes memory. You will need *at least* 64Mb for WinNT and 32Mb for Win98. Double that for reasonable performance. Currently I use WinNT on a dual-pentium 400 with 256Mb of memory. On the other hand, my kitchen PC is a pentium 120 with 80Mb of memory. QCharts runs very nicely there also.
What is your OS?
