translating scene geometry for Vray takes times

[asin_asinn]

Hi, is there a way to speedup translating scene geometry for Vray ? it can takes time to 7min to translate & compiling geometry, the actual render itself is fast less than 7min. we dont have any displacement enable.
currently we using maya 2016 extension 1 SP5, with vray core 3.52.03, win 10, 32gb of ram, the scene not eat all the ram, there still plenty of space.
Vray primitives 20.252.278

For starters, check if you've set a dynamic memory limit (Settings>System) that could be limiting memory usage. If so, set a value of 0, meaning that all available RAM will be utilized. If that doesn't help, however, it may be best to send the scene to support@chaosgroup.com for further analysis.

Hi aleksandar, the dynamic limit already set to 0
