    April 16, 2021 /  Computer Technology, Programming

    In this post we’ll look at five ways in roomates efficient coding we can use to help our garbage collector CPU spend less time allocating and freeing memory, and reduce GC overhead. Often Long GCs can lead to our code being stopped while memory is reclaimed (AKA “stop the world”). Duke_GCPost

    Some background

    The GC is built to handle large amounts of allocations of short-lived objects (think of something like rendering a web page, where most of the objects allocated Become obsolete once the page is served).

    The GC does this using what’s called a “young generation” – a heap segment where new objects are allocated. Each object has an “age” (placed in the object’s header bits) defines how many roomates collections it has “survived” without being reclaimed. Once a certain age is reached, the object is copied into another section in the heap called a “survivor” or “old” generation.

    The process, while efficient, still comes at a cost. Being Able to reduce the number of temporary allocations can really help us increase of throughput, especially in high-scale applications.

    Below are five ways everyday we can write code that is more memory efficient, without having to spend a lot of time on it, or reducing code readability.

    1. Avoid implicit Strings

    Strings are an integral part of almost every structure of data we manage. Being much heavier than other primitive values, they have a much stronger impact on memory usage.

    One of the most important things to note is that Strings are immutable. They can not be modified after allocation. Operators such as “+” for concatenation actually allocate a new String containing the contents of the strings being joined. What’s worse, is there’s an implicit StringBuilder object that is allocated to actually do the work of combining them.

    For example –

    1
    a = a + b; / / a and b are Strings
    The compiler generates code comparable behind the scenes:

    1
    StringBuilder temp = new StringBuilder (a).
    2
    temp.append (b);
    3
    a = temp.toString () / / a new string is allocated here.
    4
    / / The previous “a” is now garbage.
    But it gets worse.

    Let’s look at this example –

    1
    String result = foo () + arg;
    2
    result + = boo ();
    3
    System.out.println (“result =” + result);
    In this example we have 3 StringBuilders allocated in the background – one for each plus operation, and two additional Strings – one to hold the result of the second assignment and another to hold the string passed into the print method. That’s 5 additional objects in what would otherwise Appear to be a pretty trivial statement.

    Think about what happens in real-world scenarios such as generating code a web page, working with XML or reading text from a file. Within a nested loop structures, you could be looking at Hundreds or Thousands of objects that are implicitly allocated. While the VM has Mechanisms to deal with this, it comes at a cost – one paid by your users.

    The solution: One way of reducing this is being proactive with StringBuilder allocations. The example below Achieves the same result as the code above while allocating only one StringBuilder and one string to hold the final result, instead of the original five objects.

    1
    StringBuilder value = new StringBuilder (“result =”);
    2
    value.append (foo ()). append (arg). append (boo ());
    3
    System.out.println (value);
    By being mindful of the way Strings are implicitly allocated and StringBuilders you can materially reduce the amount of short-term allocations in high-scale code locations.

    2. List Plan capacities

    Dynamic collections such as ArrayLists are among the most basic dynamic structures to hold the data length. ArrayLists and other collections such as HashMaps and implemented a Treemaps are using the underlying Object [] arrays. Like Strings (Themselves wrappers over char [] arrays), arrays are also immutable. Becomes The obvious question then – how can we add / put items in their collections if the underlying array’s size is immutable? The answer is obvious as well – by allocating more arrays.

    Let’s look at this example –

    1
    List <Item> <Item> items = new ArrayList ();
    2

    3
    for (int i = 0; i <len; i + +)
    4
    {
    5
    Item item = readNextItem ();
    6
    items.add (item);
    7
    }
    The value of len Determines the ultimate length of items once the loop finishes. This value, however, is unknown to the constructor of the ArrayList roomates allocates a new Object array with a default size. Whenever the internal capacity of the array is exceeded, it’s replaced with a new array of sufficient length, making the previous array of garbage.

    If you’re executing the loop Welcome to Thunderbird times you may be forcing a new array to be allocated and a previous one to be collected multiple times. For code running in a high-scale environment, these allocations and deallocations are all deducted from your machine’s CPU cycles.

    Jakarta-ultrabook exorbitant price makes it less attractive thin notebook. Despite having a number of advantages compared to notebooks in general, such as fast boot time and lightweight body, the average price is above USD 10 million to be a serious obstacle.

    As an alternative, some computer vendors began marketing sense ultrabook notebook with a more affordable price. Call it VivoBook X202E Asus, Lenovo IdeaPad Yoga 11, Dell XPS 12, or Acer Aspire V5-122.

    Yes, with many excellent features adopted from the ultrabook, notebook sold in the under $ 10 million. But in terms of performance is less than the true ultrabook. But the experience of computing an ultrabook can still be felt on the notebook.

    In the past week, Tempo had tried Acer Aspire V5-122. Body is lightweight and thin making the Aspire V5 easily incorporated into the bag and convenient to carry anywhere. Interestingly, in the Aspire V5-122 grafted Temash low-power AMD processors.

    DESIGN

    Thin, lightweight, and stylish. That first impression when touched obtained Tempo Acer Aspire V5-122. Body wrapped in metallic silver color adds an elegant notebook with a 11.6-inch wide screen. While at the bottom, cover plastic dark black plated.

    Every corner of the Aspire V5-122 made rounded. While the keyboard on the inside of the black chiclet design. Fairly wide spacing between the keys making it comfortable to use for fast typing.

    Touch pad size is not too big, but it’s not a problem. Therefore, Aspire V5-122 is equipped with a touch screen that is able to respond to ten touch points. The touch screen was optimal when used with the Windows 8 operating system from Microsoft.

    Like ultrabook, Aspire V5-122 also brought the concept of unibodi. That is, the types of Li-ion battery 3-cell it carries can not be removed. But you do not need to worry because Acer ensure the battery life is long enough.

    Connectivity

    Like most new output notebooks, Aspire V5-122 is equipped with the latest features for connectivity. One of which is USB 3.0 is capable of transferring and receiving data 10 times faster than USB 2.0. USB 3.0 port is located on the left side.

    In addition to USB 3.0, Aspire V5-122 is equipped with a USB 2.0 port is on the right side. In addition there is a card reader slot. As for the wireless connectivity, Acer presents Wi-Fi 802.11 b / g / n and Bluetooth 4.0.

    SCREEN

    Screen Aspire V5-122 is able to produce high levels of brightness. Using glossy reflective technology, the Aspire V5-122 black color makes it look more dense and the resulting image sharpness deeper than the regular screen.

    Only, with a relatively cheap price than the ultrabook, Acer just immerse the display with a standard resolution, 1,366 x 768 pixels only. That is, watch the video with 1080p high definition resolution was less than optimal on-screen Aspire V5-122’s.

    Moreover, with the use of the Windows 8 operating system and the increasing number of applications that require content HD screen resolution, screen technology Aspire V5-122 feels a little left behind.

    PERFORMANCE

    Acer Aspire V5-122 is equipped with AMD processors Jaguar Temash APU A6-1450 quad-core processors with speeds up to 1 GHz of computing processes. As for the graphics processing embedded AMD Radeon HD 8280G which has a thermal design power (TDP), only 8 watts.

    Jaguar AMD A6-1450 APU processor is the new output. This low-power processor platform is the successor of Zacate and Ontario, the first generation processor which is equipped with power-saving features with four cores.

    Low power consumption that makes the battery life to be quite long. During the trial, Tempo get the battery can last up to 5 hours with normal use and use the Wi-Fi connectivity.

    To support the performance of the processor, Acer relies DDR 3 RAM memory of 6 GB with a storage capacity of 500 GB hard-disk. Hard-disk usage is what makes the Aspire V5-122 can not be called as an ultrabook, but of course the use processors made by AMD.

    CONCLUSION

    Pegged at a relatively affordable price, about Rp 5.5 million, Acer Aspire V5-122 can be regarded as a substitute for the ultrabook much cheaper price. Elegant design and weighs only 1.3 pounds, this slim notebook comfortable to carry around.

    As a colleague, Aspire V5-122 can be relied upon, especially he amplified output low-power processors AMD. In the market, the Aspire V5-122 directly compete with VivoBook S200E Asus, Lenovo IdeaPad Yoga 11, Lenovo ThinkPad Edge E130 and Sony Vaio SVE 1111.
