Performance issues with ~20k policies

Was wondering if anyone else is experiencing a slow down even with a relatively low number of policies.

For our ~20k policies we notice it takes around 5 seconds to evaluate them.

Here is our conf.

[request_definition]
r = type, resourceId, userId, action

[policy_definition]
p = type, resourceId, userId, action

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = r.type == p.type && r.resourceId == p.resourceId && r.userId == p.userId && r.action == p.action

We have seemed to narrowed it down to this line in coreEnforcer.ts

Switching from compileAsync to compile and removing the await brought us down to around 40ms with the same amount of policies.

@hsluoyz, I think @dreamdevil00 provide the solution is good. But in Casbin, If matcher has async function and using compile , the enforce doest not provide the correct result.

v3.0.5 has been published to npm.

Use enforceWithSyncCompile instead of enforce.
