To this end, we have prepared a comparison between the SUSE Linux Enterprise 12 operating system and RedHat Enterprise Linux 7.0. I believe this will help you understand the performance of the new system.
The new version of the operating system we tested this time is the Server version. This new product makes breakthr
Comparison of Java toString Performance Optimization Solutions
Who cares about toString performance? No one! Unless you have a large amount of data in batch processing, using toString produces a lot of logs. Then, when you investigate why it is so slow, you will realize that most toString methods use introspection, which can be optimized.
However, let's take a l

on Sun Solaris needs to support a large number of connections, engines such as/dev/poll or port_get () are suitable; if high throughput is required, it would be better to use the basic select () engine. Due to the inherent algorithm problems of different selection policies, elastic selection such as this is not available in the standard ace reactor/proactor mode (see appendix 2 ).
In terms of performance, our tests show that the simulation of asynchr

1. ElaborationFor the way in which map is traversed in Java, many articles recommend using EntrySet, which is more efficient than keyset. The reason is: The EntrySet method gets all the keys and value at once, and keyset gets only the set of keys, and for each key, it goes to the map to find the value in extra time, thus reducing the overall efficiency. So what's the real story?To understand the real difference in traversal performance, including the
