Replication: Cpu and Memory utilization of threads

Hi everybody
As we know that replication process uses 3 threads-
1. Master thread (Binlog Dump)
2. I/O thread
3. Sql Thread

Now I have some confusion regarding these thing --

- In peek hours what will be the cpu and memory utilization of these
threads
and if there is high load on master thread then what will be the
effects of this in mysql performance.

- if sql thread executing query on slave server and that time if we
fire a select query on same table then what will happen.Select query
will wait or not

We are using innodb tables in both master and slave

The server has a single thread of processing, running in a continuous loop, for each iteration thread sleeping for 5 seconds and than reading textual message files from a Windows Folder and applying them to a database. From an external view, the server appears to have a memory-leek, continuously consuming RAM in a near linier fashion as...

I have a Windows service that's built with .NET. The process is meant to run in the background and not suck up too much CPU time.

I stuck some Thread.Sleep calls in a various places in the code, but that doesn't help much, since the service makes...

Does anyone know of a way to pin point true memory utilization on a per object / allocation basis in dot net. The problem that i'm having is projecting the amount of memory that will be required by an application. Obviously there is a component size (i.e. a class that is using 2 32bit integers will use 8byte) but then there is a question of overhead for .NET management (i.e. vtables, lookup tables, garbage collector pointer on a per...

I have a C# application written as a Windows Service. It spawns a number of threads, each thread has very large memory intensive processes running on it. I can keep adding threads as long as the "committed byte" utilization of the server stays below 2.5 gigs As soon as we go over that amount we receive "System.OutOfMemoryException" exceptions. I'm not sure what causes the 2.5 gig limit but we consistently hit it on all of our ...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
