7 zip decompression speed

Which is OK. The error correction features such as bit error correcting Huffman or Hamming codes are not implemented in 7ZIP yet well its only year That means the archiver can only check if the archive is corrupt via CRC methods, but can not correct the error. Our backup of the "visual SVN repository", which is made from multiple small files, was taking between 50 and 60 minutes. And, during these 50 minutes, all our servers were very slow because of the hard drives seeking.

Now, everything remains very fast during those five minutes. For everything you do on a machine, the hard drive activity will always be slower than your CPU capacity.

You can increase disk performance by disabling parallel activities and making sure that the hard drive reads and write your files one by one serially. Also it's better to read from disk1 and write your ZIP to disk2, as the physical head does not move from read to write.

In my company, we are working with an old version of 7-zip 4. This is working fine, but after just having upgraded to the newer version This happens because at each foreach cycle 7zip creates a temporary file that is as large or larger than the original one, then add new file inside them.

I have tried with cases in which there are two or more directories large some MB and one large many GB and the saving of time is in the order of several minutes. This isn't always possible. Sign up to join this community. The best answers are voted up and rise to the top.

So I compress the files first then the speed of transferring one file is fast. But now I have met the problem: the low speed of decompressing. Is there any ways to copy the huge numbers of files from local hard disk to nas fast? Forget about the compressed file, that's a dead end.

Go back to looking for good solutions to your original problem -- how to transfer a large number of files to a NAS device. Daniel B Daniel B Sign up or log in Sign up using Google. Sign up using Facebook.
