Performance of an external datagroup versus a local datagroup?

Hi,

 

 

Is there any expected difference in performance of a ~10k list of networks/hosts if the datagroup is defined in an external file versus locally, directly in the bigip.conf? This is for 9.4.8 if it matters.

 

 

I'm guessing that the lookup will be handled the same once the datagroup is loaded in memory regardless if whether it's coming from an external file versus the bigip.conf. But I figure I'd ask. I'll also try testing to see if I notice any difference in the timings for the two different datagroups.

 

 

Thanks,

    Bumping this question. I have the same. But, alas, no answer has been posted.

    The original question was from 2010, so answering Brad new update, and consequently 2010 question. :P

     

    I can provide a theoretical answer, but you will have to test in practice and compare the speed.

     

    From a TMM point of view, a local datagroup and an external datagroup should be the same, they should both be cached (not sure if in each TMM, or MCPD). So, the speed should be the same.
