Subtables, performance and resouces

Hi,   I know that subtables should be be used sparingly because each subtable is pinned to TMM instance that created subtable - so it's using RAM of this TMM - could create uneven RAM consumption...

Hi Piotr,

 

using a [expr {[crc32 $COOKIE_VALUE] % $NUMBER_OF_TABLES}] to splitt the master table would work like a charm and is always safe to use.

 

Using a [string range $COOKIE_VALUE 0 0] would be little faster, but it's not as variable (e.g. configurable table number) as CRC and also strongly depends on the format of the provided cookie values.

 

Cheers, Kai
