Solve VMware below CentOS a problem with a slow or too fast clockIn a VMware virtual machine, because the time is not synchronized with the real clock, there are many problems in development, such as Makefile files that cause unnecessary duplication, and even some programs refuse to compile. I tried to run ntpd to sync the clock, but often because of the erro

interrupt rate. 100Hz is adequate for most applications in a Linux guest. see the documentation for your Linux distribution for detailed instructions on how to build and run a custom kernel. before recompiling the guest kernel, locate the following line in/usr/src/linux-2.6/include/asm-i386/Param. h:# Define hz1000 Change the value of Hz to 100:# Define hz100 A different way to deal with a slow guest clock is to increase the host timer interrupt rate

compatibility and supports a wide range of operating systems.BusLogic driver supports all guest systems, can operate 1kb small files, if your application does have a lot of such small files, this driver is really good, but this driver is not the best option to mention high performance, if you care about performance, it is highly recommended to use LSI driver, This can greatly improve

This article describes the PHP performance analysis of php-fpm slow execution log slow logs usage. Share to everyone for your reference, specific as follows: As we all know, MySQL has slow query log, and we can tell that those SQL statements have performance problems based

In the company, in order to make full use of server performance, I installed a VMware Server2.0 on the server, is really convenient, and free, and stable, after a series of tuning, the speed is very good (specific tuning process, query my previous post), a computer changed a lot of servers (that is, hard disk IO is limited, Back to apply for a hard drive).Recent commissioning of the system found that the ho

can affect performance because it is Java-based. If you must install the Director agent, add at least 50MB of memory to the console system. If there are other agents, add the memory accordingly. Although there are no more parameter configurations for the console system, there are some things to know if the ESX server hosts more than 60 virtual systems or if there is a heavy load. In this case, the console system is very

time to solve the problem. In particular, the key service host services, such as DNS host, RADIUS authentication host, Mail gateway and other important equipment is reaching. Once there is a problem with the virtual center, managers are at a loss to find the underlying problem quickly and efficiently.Addressing the root causes of today's applications and virtualized infrastructures requires visibility into application services, networks, and virtualized architectures that apply to the various d

VMware has recently released the latest version of VMware Horizon View 5.2 for desktop virtualization. The original name is VMware View, and the new product is renamed VMware Horizon View
