迅雷官方分析：为什么下载速度慢/卡99%/电脑卡？_我的网站

A | 1月11日：在当今快节奏的互联网时代，下载也面临着新的问题：使用机械硬盘的计算机“磁盘读写性能”无法跟上。    He was considered the most handsome star of his era and she was said to be the most beautiful actress. No wonder the jodi of Dharmendra and Sharmila Tagore managed to pull in the crowds in droves with every release. They had an easy camaraderie going on screen and complemented each other to a T.     Today, as we mark Dharmendra's first birth anniversary, there is even deeper poignancy in celebrating this golden pair, who also happened to share the same birthday, December 8. On this heartfelt occasion, Filmfare looks back at the most celebrated movies, where the golden couple starred together.     In This Article      Anupama (1966)Devar (1966) Mere Hamdam Mere Dost (1968)Satyakam (1969)Yakeen (1969)Chupke Chupke (1975)Ek Mahal Ho Sapno Ka (1975) Sunny (1984)Anupama (1966)          Directed by Hrishikesh Mukherjee, the film is considered a classic of Indian cinema and marked an important milestone in the careers of both the director and the lead actress, Sharmila Tagore. The film revolves around Anupama (Sharmila Tagore), a shy and introverted young woman who faces emotional struggles due to her rejection by her father as her mother died during childbirth. The story takes a turn when Anupama meets a kind and understanding man, Ashok (Dharmendra). He brings her out of her shell, helping her realize her own worth. The music of Anupama was composed by Hemant Kumar, with lyrics written by Kaifi Azmi. The soundtrack features the timeless song Ya dil ki suno, sung by the director himself, as well as Kuch dil ne kaha, and Dheere dheere machal, both sung by Lata Mangeshkar.     Devar (1966)          It’s an emotional drama directed by Mohan Segal The movie stars Dharmendra, Sharmila Tagore, and Raaj Kumar in key roles. The film is based on the short novel Naa by the Bengali writer Tara Shankar Bandopadhyay. The film had the often repeated plot of childhood lovers separated later in life but at the time, its emotional story appealed to the audience, turning it into a hit. Dharmendra starred as a man who goes on a self-destructive spree and Sharmila Tagore played a woman who is hell bent to get justice for her murdered husband. The film had music by Roshan and lyrics by Anand Bakshi. It had some good sad tracks like Aaya hai mujhe phir yaad and Baharon ne mera chaman loot kar, both sung by Mukesh.     Mere Hamdam Mere Dost (1968)          Directed by Amar Kumar, the film starred Rehman, Mumtaz and Om Prakash besides Dharmendra and Sharmila Tagore. The film has all the hallmarks of being a melodramatic thriller, with lost and found moments and other twists aplenty. Dharmendra plays a poor but honest young man who is horrified (yes!) to know that his girlfriend was only pretending to be poor but is actually super rich. Sharmila Tagore spends the rest of the film trying to woo him over once again. Dark revelations kind of derail their relationship but things get alright in the end. The film had music by Laxmikant-Pyarelal and lyrics by Majrooh Sultanpuri. The musical love story had lovely songs like Chalkaye jaam, Hui shaam unka khayal aa gaya and Na ja kahin ab na ja, sung by Mohammed Rafi, as well as Chalo sajna jahan tak jahan chale and Allah ye ada, sung by Lata Mangeshkar.     Satyakam (1969)          Directed by Hrishikesh Mukherjee, it features Dharmendra in the titular role. The film is a poignant and powerful drama that explores themes of integrity, honesty, and the struggle to maintain one's ideals in a corrupt world. It’s based on a Bengali novel of the same name by Narayan Sanyal. It’s said to have one of the finest performances by Dharmendra, who plays a man who sticks for the truth, whatever the circumstances may be. Sharmila Tagore plays a woman who has been raped earlier in life and pines for a sedate life. She has problems with her husband, who is aware of the truth. They somehow fail to lead a contented life, because of his too honest nature and also because of the secret they share. Sanjeev Kumar plays the role of a wordly wise friend who tries to make the protagonist see reason, while Ashok Kumar plays the family elder who finally learns the importance of forgiveness towards the end.     Yakeen (1969)          Much before Don and even The Bourne Identity, came this thriller, directed by Brij Sadanah, about a man posing as his doppelganger. Dharmendra acted as both Rajesh, an innocent man on the run and Garson, the gangster who poses as him. Sharmila Tagore plays Rita, Rakjesh’s love interest, who is pregnant with his child. While the plot is all over the place, the negative role played by Dharmendra, with blue contact lenses and changed voice offered something new to the audience. It’s the most villainous role played by the actor ever.     Chupke Chupke (1975)          Directed by Hrishikesh Mukherjee, the film is known for its light-hearted plot, clever humor, and exceptional performances from its cast. A remake of the Bengali film Chhadmabeshi, it stars Dharmendra, Amitabh Bachchan, Sharmila Tagore, Jaya Bachchan, Om Prakash, Usha Kiran, David Abraham Cheulkar, Asrani and Keshto Mukherjee. Dharmendra plays a professor of Botany called Parimal, who with the help of his friends Sukumar (Amitabh Bachchan) and Prashant (Asrani), wife Sulekha (Sharmila Tagore) and uncle Haripad (David), plays a prank on his brother-in-law Raghav (Om Prakash). One hilarious situation follows the other as Parimal and company try to stretch the joke as long as possible. Both Dharmendra and Amitabh Bachchan had established themselves as action stars in the ’70s and Chupke Chupke showed that they possess great comic timing as well. Dharmendra and Sharmila gave off newly married couple vibes without resorting to any cheap tactics. It’s a family entertainer which can be enjoyed on a loop even now.     Ek Mahal Ho Sapno Ka (1975)          This is a rather forgettable formulaic film, directed by Devendra Goel, revolving around mistaken medical reports. Vishal (Dharmendra) and Aruna (Sharmila Tagore) are in love. Aruna gets to know that she might lose her eyesight in six months and breaks off the relationship, without telling Vishal the reason. Sonia (Leena Chandavarkar), falls for Vishal. Later Aruna gets to know she was misdiagnosed but still doesn’t tell Vishal the truth, thinking he’ll be happy with Sonia. Much twists and turns later, ultimately Sonia sacrifices her love to bring together the estranged lovers. The film has hummable songs such as Dekha hai zindagi ko, sung by Kishore Kumar and Dil mein kisi ke pyar ka, sung by both Lata Mangeshkar and Kishore Kumar. It had music by Ravi and lyrics by Sahir Ludhianvi.     Sunny (1984)          Directed by Raj Khosla and starring Dharmendra, Sharmila Tagore, Waheeda Rehman, Sunny Deol and Amrita Singh, the film’s story revolves around themes of family, loyalty, and emotional conflict. Inderjeet (Dharmendra) is married to Gayatri (Waheeda Rehman) but is in love with Sitara (Sharmila Tagore). She bears his child, Sunny (Sunny Deol), who is brought up by Gayatri as her own son, after Inderjeet passes away. Sunny falls in love with Amrita (Amrita Singh), who happens to be Sitar’s niece. The film had some lovely music by RD Burman and lyrics by Anand Bakshi. It had memorable songs like Jaane kya baat hai, sung by Lata Mangeshkar and Aur kya ahd-e-wafa hote hain, sung by both Suresh Wadkar and Asha Bhosle. This was the last film done together by this golden couple. They were supposed to be cast together in Karan Johar’s Rocky Aur Rani Kii Prem Kahaani (2023) but Sharmila’s ill health at the time prevented that. Her role was ultimately essayed by Shabana Azmi.     Also Read: Throwback: Dharmendra & Sharmila Tagore were to star in Gulzar’s Devdas。当下载速度非常快时，使用机械硬盘的计算机可能会因为磁盘太忙而出现问题：下载速度突然减慢，计算机响应减慢，下载进度卡为99.9%。怎么了？迅雷官方解释了为什么下载速度突然减慢，电脑响应速度减慢，下载进度卡在99.9%等。下载速度突然减慢：迅雷下载文件时，为了避免频繁向磁盘写入数据，磁盘读写性能下降。

B | 因此，迅雷的下载引擎首先将下载的数据保存到计算机的内存中。当积累了足够的数据时，它们会一起写入磁盘。这是迅雷下载引擎的“磁盘缓存”功能。由于通过网络下载数据比将数据写入磁盘慢，因此可以确保池中的水不会溢出。但是如果池溢出，就会引起问题。它体现在迅雷的下载引擎中，会导致程序崩溃等异常现象。近年来，随着网络带宽的增加，下载数据的速度开始出现快于将数据写入磁盘的速度。当迅雷的下载引擎发现磁盘缓存快满时，它会自动降低下载数据的速度。让下载的数据尽快写入磁盘，在腾出足够的缓存空间后恢复原来的下载速度。如果您的计算机使用的是机械硬盘，并且正在高速下载，下载速度会突然减慢。

C | 可能这就是原因。电脑反应慢下来：要深入了解这个问题，我们必须从“机械硬盘”的“先天缺陷”开始。

D | 首先看一张机械硬盘拆卸图。当“机械硬盘”读写数据时，上图中的“音圈电机”转动“磁头摆臂”，使摆臂顶端的“磁头”从“磁盘”表面高速飞行约1纳米，在“磁盘”上读写数据。圆盘的表面看起来像一面镜子，实际上是由环连接的“轨道”组成的。

E | 当需要读写的数据存储在磁盘的不同“磁道”上时，磁头摆臂在磁盘上来回摆动，使磁头在存储相应数据的磁道上飞行。

F | 这种行为被称为“寻找”。由于头部摆臂是由音圈电机控制的纯机械结构，因此从发出指令到摆臂完成跟踪的响应时间约为10毫秒。相比之下，机械硬盘磁头当前位置数据的读写时间仅为寻道时间的0.1%，频繁的寻道操作会降低机械硬盘的响应速度。这种“先天性缺陷”创造了机械硬盘的一个主要特征（随机读写比顺序读写慢得多）。例如，顺序读写的速度可以达到100Mb/s，但随机读写的速度只能达到500kb/s，仅为顺序读写的0.5%。理想情况下，当迅雷高速下载数据时，机械硬盘会努力将迅雷下载的数据写入磁盘。但事实上，计算机中不仅运行一个软件。其他软件，包括操作系统，也会产生读写磁盘的需求。其它软件读取和写入的磁盘数据往往位于其它磁道上，这将频繁地触发机械硬盘的“寻道”操作。因此，机械硬盘陷入了“随机读写”的泥潭，这不仅降低了霹雳的数据写入速度，而且降低了用户在计算机上操作其他软件时的整体响应速度。很多网友不知道99.9%的人下载了进度卡。事实上，在下载数据的过程中，迅雷会实时检查下载的数据，避免下载错误的数据。数据验证过程需要一定的时间才能完成。幸运的是，在大多数情况下，数据的下载速度比数据验证的速度慢。因此，当数据下载完成后，验证数据的过程也可以同时完成。下载任务能够顺利完成。但是，当网络下载数据的速度超过数据验证的速度时，等待验证的数据将生成积压。下载的文件越大，下载速度越快，需要验证的数据积压越多。此时，如果添加前两个问题，则检查积压数据的速度将变慢。当下载任务的文件数据已经下载，但仍有大量未更正的数据积压时，迅雷的下载引擎会将任务调度保持在99.9%，直到所有下载的数据都被检查完毕，任务才会被下载。所以当你观察到迅雷有很快的下载速度时，却突然失去了速度，当任务进度达到99.9%时，迅雷上出现“磁盘忙”的提示，这可能就是为什么。然而，应该注意的是，还有许多其他原因可能导致99.9%的下载进度卡，这只是其中之一。
