[mkgmap-dev] Java tuning hint

Thu Jul 24 15:01:59 BST 2014

Hi Felix,

in splitter we don't use intern(), so this parameter should have no effect.
Also, I only saw an effect on my netbook, maybe under special circumstances,
because I was not able to reproduce it later. So sorry for the noise.

Hi everyone,
Actually - just to bring this up again - did not have any time at the time this was written..

Did you by chance also test if this parameter speeds up mkgmap splitter?

Felix

the same value here

bernd at apoll:~> java -XX:+UnlockDiagnosticVMOptions -XX:+PrintFlagsFinal -

version | grep StringTable

     bool PrintStringTableStatistics                = false

{product}

    uintx StringTableSize                           = 60013

{product}
