The fact is that if autotests are still being written to maintain quality in some web projects, then few people are involved in performance control at the development stage in principle. A web project with both autotests and code benchmarks is a rarity. Developers are much more likely and for reasonable reasons to use the following heuristics with a good value-for-money ratio:
- queries to MySQL (further we will cite this popular database as an example) go through a fairly adequate API that uses indexes (although we do not see exactly how indexes are used by the scheduler and what their cardinality is)
- the results of executing queries to the database and heavy pieces of code are cached
- the developer checked the construction of the web page 3.14 times in the browser, and if it doesn’t slow down at first glance, then everything is OK
Let’s take caching. The developer often has no time to think about how often the cache can be rebuilt. But in vain. For example, if it takes a long time to rebuild the product catalog cache and the cache is reset when one product is added, then caching will do more harm than good.
That is why it’s not recommended to use the built-in MySQL query cache, which suffers from a similar problem: the table cache is completely flushed when at least one record of the table changes (imagine a table with 100 thousand rows, and the absurdity of the situation becomes obvious).

Network connectivity is essential for the emerging business planet. Network engineering is essential in establishing and sustaining the network connectivity capability at universities, corporations, and hospitals. It is a vast field that is certainly a major part of the planet of computer systems, telecommunication and radio technologies.
Function Of Network Engineers
Network engineering in telecommunication involves the internetworking service components for switched networks and executing and establishing software and hardware to meet the needs. In the sphere of computers, network engineering offers using the development of application and hardware expected to complete the pc design network goal. In radio communication, network engineering is involved in the creation of network topologies. Its role in computing involves the creating, maintenance, and administration of pc networks.
This practice varies from business to firm and regularly entails troubleshooting hardware and computer software and delivers software program help and system evaluation and design. Commonly, you’ll find 4 forms of pc networks: Wide Location Network or WAN, Neighborhood Location Network or LAN, Global Region Network or GAN, and Metropolitan Area Network or MAN. Network engineers are expected to set up a network for the client. They operate with the network manager to configure and design systems that manage and boost efficiency, to meet the business requirements of the consumers. The engineers are anticipated to be involved in day-to-day administration from the installed system.
