Casbin causes severe lag

after adding access control using Casbin, my app becomes very laggy. code snippet of my accessControlProvider.ts:

import { AccessControlProvider } from "@refinedev/core";
import { newModel, StringAdapter, newEnforcer } from "casbin";
import { IAccessControlRule } from "interfaces";
import { store } from "redux/store";

const model = newModel(`
[request_definition]
r = subject, object, action

[policy_definition]
p = subject, object, action, eft

[role_definition]
g = _, _

[policy_effect]
e = some(where (p.eft == allow)) \
&& !some(where (p.eft == deny))

[matchers]
m = g(r.subject, p.subject) \
&& regexMatch(r.object, p.object) \
&& regexMatch(r.action, p.action)
`);

export const accessControlProvider: AccessControlProvider = {
  can: async ({ resource, action, params }) => {
    const role = store?.getState()?.user?.role;
    const accessControlRules = store?.getState()?.temp?.accessControlRules;

    const ruleString = accessControlRules
      ?.map((item: IAccessControlRule) => {
        return `p, ${item?.role}, ${item?.route}, ${item?.permissions?.join(
          "|"
        )}`;
      })
      ?.join("\n");

    let targetUrl = params?.route || resource;
    if (targetUrl?.charAt(0) === "/") targetUrl = targetUrl.slice(1);

    const adapter = new StringAdapter(ruleString || `p, guest, /, *`);
    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, targetUrl, action);

    return Promise.resolve({ can });
  },
};

import { AccessControlProvider } from "@refinedev/core";
import { newModel, StringAdapter, newEnforcer } from "casbin";
import { IAccessControlRule } from "interfaces";
import { store } from "redux/store";

const model = newModel(`

      ?.map((item: IAccessControlRule) => {
        return `p, ${item?.role}, ${item?.route}, ${item?.permissions?.join(
          "|"
        )}`;
      })
      ?.join("\n");

    let targetUrl = params?.route || resource;
    if (targetUrl?.charAt(0) === "/") targetUrl = targetUrl.slice(1);

    const adapter = new StringAdapter(ruleString || `p, guest, /, *`);
    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, targetUrl, action);

    return Promise.resolve({ can });
  },
};
