; by observing, in this case, there is no hardware bottleneck in the problem.2, network bottlenecks, can be determined by viewing the network utilization, a lot of ways, here is not introduced; but if it is in the LAN, and this is just a Web service type Web site, and the video class site is different, so in this case there is no network problem3, Linux operating system bottlenecks, Linux on the performance of the design to the kernel parameters too m

even untimely, it should be understood. has been in the Java community for nearly 3 years, for some performance tuning topic I have been stuck in the mouth, just for last night saw a performance tuning article, I can't help it .Tomcat Performance Tuning:Locate the Conf direc

Tuning OverviewMost spark job performance is mainly consumed in the shuffle link, because this link contains a lot of disk IO, serialization, network data transmission and other operations. Therefore, if you want to make the performance of the job to a higher level, it is necessary to tune the shuffle process. But it's also important to remind you that the factor

Label:I believe a lot of friends, whether it is to do development, architecture, or DBA, are often heard of the word "tuning". Talk about "tuning", may make a lot of technical staff heart passion, also may make a lot of people feel distressed, do not know how to start. Of course, there are many people who are dismissive of this, because not everyone does the project is very high

. When a query is executed, SQL Server does not read more or less data than is actually required, so when executing the same query on the same dataset, the resulting logical read numbers are always the same.Why is it important to know the logical read value of SQL Server when executing queries in tuning query performance? Because this number does not change each time the same query is executed. So, when it

AnglarJS, as an excellent Web framework, can greatly simplify the burden of front-end development.

OverviewØ The thinking of performance optimizationThe first is a more accurate positioning problem, with the help of the corresponding toolkit, the analysis of the system performance bottlenecks, in accordance with its performance indicators, and the level of decision-making choice of the way to optimize. In the selection of the method of optimization, we can ref

Linux performance tuning 5: tuning an important role in soft raid storage. RAID independent redundant disk arrays are classified into two types: raid card-based hard raid (hardware implementation, high speed, suitable for large applications), system-based soft raid (generally included in the kernel, performance is not

The last 2 months have been doing mobile phone and TV development, the development process encountered a variety of pits. Get fast New Year's day, finally put on the line. 2 months to dry down full of hard work, not so busy with their own preparation of the front-end performance tuning summary below, in order to facilitate the use of their own once again to be handy. Referring to the high-

;Most disk configurations are based on capacity requirements rather than performance;The cheapest solution may be a small number of large-capacity disks;The second most common problem is having too handle logical disks on the same array.This increases seek time and significantly lowers performance.The disk subsystem is discussed in 4.6, "Tuning the disk subsystem" on page 112.The second common problem is th

Check 12 Performance Tuning commands in linuxGuidePerformance Tuning is one of the most important tasks for O M engineers. If your production environment experiences slow system response speed, abnormal hard disk I/O throughput, and the data processing speed is lower than the expected value, or if the CPU, memory, hard disk, network, and other system resources a

Why do you want performance tuning? Most Linux distributions are designed to be fully compatible with most computers in the marketplace. This is a fairly mixed set of hardware (hard drive, video card, NIC, etc.). So Red Hat, Suse,mandriva and some other distribution vendors have chosen some conservative settings to make sure the installation is successful.Simply put: Your distribution is running well, but
