When setting the percentages for PercentAvailSysResources on multiple Domino servers, do I need to make sure that the percent assigned to each server is large enough to allow enough memory for the size defined in the NSF_BUFFER_POOL_SIZE_MB setting (or least sufficient to allow 750 MB)?
Couple of things here. The Percent AvailSystResources is "discouraged" by Lotus as a setting for a Domino 5.0.12+ (including 6 and 7) servers. Second, the NSF_BUFFER_POOL_SIZE_MB setting takes precedence anyway if both settings are used.
There are a couple of good resources that I can point you to that explain these variables and their effect on performance, rather than replicating that information here.
Professor.INI on Notes.Net has written about the topic a couple of times, see the following links:
Those articles also point to a great tech description written by Scott Hopper of IBM (Lotus).Hope this helps.
