ERPNext is slow when fetching data


My ERPNext is too slow when i tried to fetch data.
Is there any Multithreding option do i need to enable. As i seen i have 4 core CPU but ERPNext is not using all of that.

Try the slow query log. Queries usually can’t be multi-threaded. You can improve performance by indexing. Also check innodb_buffer_pool_size, should be 50-60% of your memory
