Re: InstantDB: IntantDb Settings and Documentation


Norman

I agree. A section on the optimal settings for various performance 
objectives is a good idea. In the mean time, I think these are the best 
settings for using least memory.

cacheAmount=0
cacheCondition=CACHE_ROWS
systemCacheSize=0
systemCacheCondition=CACHE_ROWS
resultsOnDisk=1
resultsSetCache=CACHE_ROWS
resultsSetCacheAmount=0
rowCacheSize=16
singleRowCount=1
systemRows=0
controlColCacheSize=16
traceLevel=0

In addition, if you want IDB to do garbage collection (3.26 only)
then set:

garbageCollectStatements=10
garbageCollectPercent=70

Also, if the data is read only, then set:

transLevel=0

For speed - basically increase all the memory related properties and 
set:

fastUpdate=1
resultsOnDisk=1

There's not really a "best" set of values for speed. It's just a matter 
of increasing caches etc. until things don't go any faster.
