I was thinking the advantages would be the following:
1) The split of processing load as you mention
2) In order to run market internals, I need to display several charts for several instruments at once:
- Tick
- AD Line (this needs a few instruments actually to build correctly)
- Interest Rates (that's 5 yr 10yr and 20yr
- SPY/QQQQ/IWM
- Market Sectors (XLU,XLP,XLE etc..)
...and so on. This produces a huge load on the total chart refresh rate, making subsequent operations such as scanning, switching symbols and so on, slower. I was thinking that if I could separate all this stuff into another instance (separate database with ONLY required symbols, much shorter history such as 10 days instead of 10 years!), then I can get this realtime display and have my main AB running like a song.
I have tried it this US market morning and THE PROBLEM I am encountering, however is not AB! IQFeed client is crashing on me when i try this configuration. Apparently it doesn't like it. I am not sure whether to continue the tests or find another route.
cheers,

I am not sure whether this will make things better but currently the fact that I am simultaneously charting several symbols at once is putting additional load on my setup.
