Can one CPU have multiple cores?
Most computers only have a single CPU. That single CPU may have multiple cores or hyper-threading technology—but it’s still only one physical CPU unit inserted into a single CPU socket on the motherboard.
Does Windows 10 use multiple cores?
From Microsoft – Windows 10 supports a maximum of two physical CPUs, but the number of logical processors or cores varies based on the processor architecture. A maximum of 32 cores is supported in 32-bit versions of Windows 8, whereas up to 256 cores are supported in the 64-bit versions.
What is better more cores or more RAM?
More RAM means more space for your programs. It does not necessarily mean more speed or better performance. If your main concern is speed, then it’s generally better to have more cores than RAM. In this case, having multiple cores but not enough RAM translates into slowdown issues.
How to make MySQL server use more cores?
Once you set innodb_thread_concurrency to 0, you can set innodb_read_io_threads and innodb_write_io_threads (both since MySQL 5.1.38) to the maximum value of 64. This should engage more cores. This is the best guidance I ever found on how to make MySQL use more cores in general.
Is it possible to make MySQL single thread to use multicore?
The A.1.7 quote is misleading — It is only saying that multiple connections can take advantage of multiple cores. And “do the right thing” when they try to modify the same row (s).
Is it possible to make MySQL use more than one CPU?
The InnoDB tuning pages have been given an overhaul in MySQL 5.5, so there is some good info there as well. From the InnoDB disk IO tips: If the Unix top tool or the Windows Task Manager shows that the CPU usage percentage with your workload is less than 70%, your workload is probably disk-bound.
Is it possible to use more than one core?
The servers are quite hefty with an OLAP/DataWarehouse (DW) type load: Note: The biggest DB is the replicated one from the OLTP DR server and the DW is loaded from this. It isn’t a full DW: just last 6 months to 6 weeks so it is smaller than the OLTP DB. What setting or patch is required to allow more than one core to be used?
