drupal performance tuning

PrefaceThis article continues to explain how to tune the concepts that are relevant to performance optimization in the previous chapter. Code optimization is the most common of us, but there are also software architectures, JVM virtual machine tiers, databases, and operating system levels that can be tuned in various ways to improve performance. The ChaseGeneral steps for optimization:If there is a problem

; 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

access, and one point, is the index of the cluster factor, when this value is very high (perhaps a lot of friends notice that Sometimes a SQL logical reading is much larger than the whole table, that's all, even if the data you access is small, it's possible to go through a full table scan, and the cluster factor problem is almost inevitable in the case of many different fields, so, to really master the optimization, We must know and understand the basic knowledge and concepts involved in the d
