Những chương trình tăng tốc, tối ưu bộ nhớ có thực sự hữu dụng?

Rất nhiều công ty muốn bán cho bạn cái gọi là "memory optimizers" (trình tối ưu bộ nhớ) mà được xem như là 1 phần của các chương trình "PC optimization" (trình tối ưu máy tính). Những chương trình này có hại hơn là vô ích — nó không những không tăng tốc máy tính của bạn mà còn làm nó chậm đi.
Những chương trình này chỉ có thể đánh lừa được những người dùng có ít kinh nghiệm, đưa ra những hứa hẹn dối trá về tăng tốc hiệu năng của máy. Thực sự thì, máy tính của bạn tự mình có thể quản lý được bộ nhớ RAM. Máy tính sẽ dùng RAM để tăng hiệu năng của máy tính bạn — vì vậy không có lý do gì mà lại đi làm sạch RAM.

RAM của máy bạn đang đầy dần? Tốt đó!

Trình tối ưu bộ nhớ hoạt động dựa trên 1 sự nhầm lẫn tai hại. Bạn có thể thấy RAM của máy bạn đang đầy lên — lấy ví dụ, bạn có 4 GB RAM và thấy hết 3 GB bị đầy và chỉ còn lại 1 GB trống. Nhiều người có thể ngạc nhiên vì điều này — hãy nhìn xem phiên bản Windows mới thật cồng kềnh làm sao! Làm sao mà bạn có thể chạy thêm chương trình nào nữa với số lượng bộ nhớ trống ít như vậy?
Thực tế, những hệ điều hành hiện đại quản lý bộ nhớ rất tốt. 3 GB RAM bị đầy đó không phải là thừa thải. Thay vào đó, máy tính của bạn dùng RAM để cache (lưu vào bộ nhớ đệm) dữ liệu để tăng tốc độ truy cập. Bất kể là các trang Web bạn đã mở trong trình duyệt, ứng dụng bạn đã chạy, hoặc các dữ liệu khác mà bạn có thể sẽ dùng lại trong thời gian ngắn, máy tính của bạn giữ lại tất cả trong RAM. Khi mà bạn cần đến những dữ liệu đó lần nữa, máy tính sẽ không cần phải đụng tới ổ cứng của bạn — nó chỉ cần load tập tin từ RAM.

Does Memory Optimizers and RAM Boosters really useful?

Many companies want to sell you “memory optimizers,” often as part of “PC optimization” programs. These programs are worse than useless — not only will they not speed up your computer, they’ll slow it down.
Such programs take advantage of inexperienced users, making false promises about boosting performance. In reality, your computer knows how to manage RAM on its own. It will use RAM to increase your computer’s performance — there’s no point in having RAM sit empty.

Is Your Computer’s RAM Filling Up? That’s Good!

Memory optimizers are based on a misunderstanding. You may look at your computer’s RAM and see it filling up — for example, you may have 4 GB of RAM and see that 3 GB is full with only 1 GB to spare. That can be surprising to some people — look how bloated modern versions of Windows are! How are you ever going to run additional programs with so little memory available?
In reality, modern operating systems are pretty good at managing memory on their own. That 3 GB of used RAM doesn’t necessarily indicate waste. Instead, your computer uses your RAM to cache data for faster access. Whether it’s copies of web pages you had open in your browser, applications you previously opened, or any other type of data you might need again soon, your computer hangs onto it in its RAM. When you need the data again, your computer doesn’t have to hit your hard drive — it can just load the files from RAM.

Becareful, SmartBarre seem to be scam

Hi,

SmartBarre.com seem to be scam because they are not paying to member (or they pay very slow - I found on their forum said that it take about 1 year or more to be paid). I work for smartbarre for over a year, I earned enough money to made a Withdrawal Request. But I waited since Apr 01, 2013 but still no payment sent from them.

They said on their forum that they have to pay for the hosting, and they're out of money, but they said that long time ago, and they still "not enough money" when their member ask why they pay too slow. So if you want to join SmartBarre, think carefully, don't waste your time here.

MyBrowserCash is a big SCAMMER

Yes, MyBrowserCash (MBC) is a BIG SCAMMER, I work for them for over 1 year, spend a lot of money to upgrade & be able to buy more Rented Referral. And now, they delete all Rented Referral of their member, and they remove some (or almost all) their member's money. Also, the long term problem of MBC is they took 1, 2, 3 months or more to pay to their member, now they don't have money so they reduce the WITHDRAWAL AMOUNT to $19 (I request withdrawal since 11/24/2012 with $200 and now they reduce that amount to $19!!!!)..... they also don't reply to your ticket about withdrawal or something about money.

2012-12-16: We've been forced to convert some users old rental earnings to Purchase Balances. We apologize for having to do this, please remember this was written in the Rental TOS we could do this if deemed necessary.

We are also adding the ability to upgrade using Purchase Funds which should be available by Tuesday December 18th.

And a further note, our main support person had a family emergency last week which resulted in many tickets going un-answered. We are working to catch up on these tickets and put in place more support personnel. And we sincerely apologize for the delay in replying to these tickets.

NOW THEY CONVERT ALL MY MONEY IN THE ACCOUNT BALANCE TO PURCHASE BALANCE (money in purchase balance can't be withdraw). MBC IS NOW A THIEF!!! Please, police please arrest them!!

All they want is to TAKE YOUR MONEY, they want to SCAM US, TAKE OUR MONEY & RUN. If anybody could do something to make them return their member's money, PLEASE DO NOW, they have an ADDRESS on their site

After I earned my first $5, I requested for payout, and I have to wait for a month. After a month, there is no payment, I still waiting, send email to them, and also a lot of member post many topics about not being paid in the forum (me too). After that, Andy S (CPM.biz's staff) told us to send email to him with ID, and he reply to me with an email "Waiting payment from Advertisers". And now, it's been over 2 months, I receive this message:

So, please don't use CPM.biz, waste your time
