I am doing a disk to disk copy on a PC and the transfer rate is surprisingly slow. It is a Windows XP machine, which means the operating system is faster than newer generation Windows LOL (the funny part is that I am not even kidding, the XP machine is literally faster than my Windows 10 machine, is it funny or just sad?). I am using Multi Commander to do the transfer. Both of the drives are normal hard drives of sizes of about 500 GB. Many of the files are relatively small, between 50 KB and 500 KB, but some files are megabytes in size. The total number of files is about 1.2 million and the total size of the transfer is 54 GB. According to Multicommander, the average speed is 304 KB/s which seems incredibly slow to me and is taking literally days to transfer the 54 GB required. It seems like the small files are the problem because most of the time the transfer speed is listed as 4 or 8 KB/s which is INSANELY slow. I think the speed just increases exponentially when a larger file is transferred. So, if this is indeed the problem, a 4 KB/s speed on small files, what could be causing this?
I noticed that if I transfer a few large files between two hard drives, it's pretty speedy, at around at least 30&nbsp;MB per second, but if I transfer thousands of files less than 5&nbsp;KB, it is pretty damn too slow.. around 1 to 2&nbsp;MB per second.   Is there a way to speed up the copy/paste process with thousands of small files on Windows 7?
Why do PBX systems use -48 V? I'm new to Ubuntu. What's the application extension for development reasons? I know Windows is mainly .exe and Mac is .dmg or .app. Does Linux have an unique one? Pull-up and Pull-down Resistor Usage on Input or Output MCU Pins Are pull-up/down resistors (whether internal or external) only needed for MCU INPUT pins? In contrast, an MCU pin configured as an OUTPUT "knows what level it's at" because it does the driving - a "floating" MCU OUTPUT pin tied to some input of another circuit doesn't make sense, because the state of the MCU pin can only be high or low... do I have this right? Now, upon MCU bootup or failure, it may be beneficial to have a pull-up/down tied to this "MCU output to IC input" line to ensure that the input to some IC is never floating.  Maybe I just answered my own question here... pull-up/down resistors can be used on both input and output pins, depending on application? What are attributes in .NET? Is it safe to eat potatoes that have sprouted? I'm talking about potatoes that have gone somewhat soft and put out shoots about 10cm long.   Other online discussions suggest it's reasonably safe and the majority of us have been peeling and eating soft sprouty spuds for years.

It's the difference between me just putting up a door to my house, or putting up dirt instead. Add a non-breaking space to "reopen (1)" and its ilk Can a sequence which decays more slowly still yield a converging series? In Bergman's companion notes to Rudin, he says that "If a sequence of positive terms has convergent sum, so does every sequence of positive terms which decays more rapidly." So given a sequence $\{a_n\}$ of positive terms such that $\sum_n a_n$ converges, if $\{b_n\}$ is such that $$ \lim_{n\to\infty} \frac{a_n}{b_n} = +\infty, $$ then $\sum_nb_n$ converges. I can prove this given $\{a_n\}$ and $\{b_n\}$. However, can we find $b_n$ which decays more slowly, i.e. $$ \lim_{n\to\infty} \frac{b_n}{a_n} = +\infty $$ such that $\sum_n b_n$ converges?  Similarly, we have the claim "if a sequence of positive terms has divergent sum, then so does every sequence of positive terms which decays more slowly." Prove that $V = V_1 \oplus V_2$ in the following Let $V$ be a vector space over $\mathbb{C}$ such that $T^2=1_V$. Define  $V_1 = \left\{v\in V |\ T(v) = v \right\}$,  $\ V_2 = \left\{v\in V |\ T(v) = -v\right\}$  prove that $V = V_1 \oplus V_2$  For start, I've shown that $V_1\ ,V2$ are subspace of $V$. However, I'm stuck trying to show that $\forall \ v\in V,\ v = v_1 + v_2$ where $v_1 \in V1, v_2 \in V_2$.  I know at some point I have to make use of  $T^2=1_V$, but cant figure out how. Any help or insight is deeply appreciated. How can number of subdirectories and files be determined from the output of using ls -ld command?  I realize that this command only lists the directories. Finding all software packages in Debian that provide a particular alternative The Debian distribution has the . From the Wiki:     The Debian alternatives system creates a way for several programs that   fulfill the same or similar functions to be listed as alternative   implementations that are installed simultaneously but with one   particular implementation designated as the default. For example many   systems have several text editors installed at the same time. The vi   program is a classic example of an editor that has many   implementations such as nvi, elvis, vim, etc. but which one should be   designated as the default?   In general, there are multiple packages in Debian that provide a particular alternative. How does one obtain a complete list of all such packages that exist in the Debian repositories? Let us use the vi alternative as an example.  NOTE: Doing such a query against the list of installed packages is easy, but that is not what this question asks. MS word: a macro to turn ON/OFF some proofing settings What macro could turn ON/OFF some proofing settings?
