When starting a new database performance tuning project, you must first find out which query has the lowest efficiency. In other words, determine the cause of the worst performance s

Have you already used tree-shaking and code-splitting two tools in react and angular? Have you used compression techniques such as Brotli, Zofli, and Hpack, or the OCSP Protocol (online Certificate status protocol)? Do you know about resource

temporary tables are finally explicitly deleted, which avoids longer locking of the system tables. About Indexes You should first consider establishing an index on the columns involved in where and order by. When using an indexed field as a condition, if the index is a composite index, you must use the first field in the index as a condition to guarantee that the system uses the index, otherwise the index will not be used, and the field order should be consistent with the in

firmware, which can affect their load on the system. Memory Performance Tuning OptionsIf it is determined to be a memory bottleneck, you can do the following: Tune swap space using Bigpages, hugetlb, and shared memory. Increase or decrease the page size. Improved active and inactive memory handling Adjust the page-out rate Restrict the resources available to each user on the s

you put some non-important data, you can set writetowal (false) to further improve the write performance. Writetowal (false) will discard Wal log writing during put. The risk is that when the regionserver goes down, the data you put may be lost and cannot be recovered. Enable bloom Filter The bloom filter improves the read operation performance by changing the s

Selection We recommend that you specify the Column Family to reduce the traffic. Otherwise, the scan operation will return all data (all Coulmn Family) of the entire row by default ). Close ResultScanners After reading data through scan, remember to disable resulttasks. Otherwise, problems may occur on the RegionServer (the corresponding Server resources cannot be released ). Optimal Loading of Row Keys When you scan a table, you only need row key (CF, qualifier, values, timestaps are not requi

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

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

The most common disk bottleneck is that the hard disk is too small; 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 signif
