Description
I used ldap3 to query the Active Directory but looks like the library costs lots of CPU times. So I integrate yappi into my code to collect the performance statistics.
My test is query 100 entries in the AD.
The statistics show get_config_parameter costs ~15% (0.017240/0.114406) of the CPU time of the call.
I suppose it could be a good point to improve the performance by replacing the call of get_config_parameter by directly accessing the configuration items.
Any thoughts of the idea?
