It spends too much time for that A large number of regular expressions are compiled

I have a issue when compile some uri regular expressions by hyperscan,it spend 6 minutes.
Those regular expressions features:
1.About 63000 regular expressions .
2.The length of each regular expression less than 100 bytes.
And the ‘flags’ parameter of function 'hs_compile_multi' is HS_FLAG_CASELESS|HS_FLAG_DOTALL|HS_FLAG_SOM_LEFTMOST.
There have some method to improve performance of compiling regular expression?
