Request: General speed improvment

Tim

Robert, we already talked about this via email, but I wanted to repost it here, maybe someone else wants to comment on it.

As I use boxcryptor to encrypt folders on my network I run into performance bottlenecks caused by the encryption.

As I recently upgraded my network to 1 GBit this is more noticeable than ever. Unencrypted the throughput over the net is at the physical maximum (~ 90 MB/sec) and with encryption it's down to just ~ 12 MB/sec.

The CPU utilization is minimal (one core at 12%, three other cores unused), so I don't think the CPU is the bottleneck.

Yes, speed improvements are one of the (many) items on our todo-list. Even though BoxCryptor for Windows can be used with any folder, the main intention is to use BoxCryptor to secure your data before it is stored in the cloud (e.g. Dropbox, SugarSync, etc.). And other features are more important for this purpose (e.g. apps for Android and iOS).

That's why the speed issue has not a very high prio for us, as ~12-15 MB/sec is good enough for this purpose (as your internet connection is waaaayyy slower).

You could add this request to our Feedback Forum over at Uservoice (http://boxcryptor.uservoice.com/forums/100207-general) so that other users can vote on it.

I use BoxCrytor to encrypt files before storing them in the cloud (trend micro Safesysnc). However not trusting the internet connection I keep a local encrypted copy on a PC which is always on. This local version is then synced by the safesync software with it cloud server.
Because of the very slow performance before the "nonFixed" mode was introduced I added a 2nd none encrypted folder. This was synchronised through Boxcrytor by 2nd copy to the encrypted folder.
The none encrypted folder is maped on my working PC with a full speed connection isolated from any delay due to the encryption process.
I guess you could call is a proxy folder.
Apart from so silly problems with 2nd copy sysc process it works well.

Geoffw, if I get this right, you encrypt locally and then sync to the cloud.

What speeds do you get when encrypting a file locally? (MB/s ?)

Tim,
I don't see the encryption speed as I only read and write to the plain folder.
the process works as follows:

Plain folder
V
2nd copy Bidrectional sysnc
V
BoxCryptor
V
Local encrypted folder
V
SafeSync bidirectional sysnc with cloud.

The process works upward and downwards as I can add an encripted file from a remote pc the Safesysnc cloud sever and after about 5 mins it will appaer in my local plain folder.
The delay being built in to the save sysnc sofwear to prevent to much syncing of temp files.
2nd Copy is the weak link as it is not good at sencing changes coming back down from the cloud through boxcrytor. I am looking at replacing it with Freefilesync realsync option.

If Boxcrytor had the option to revers the direction of the encription ie so the mounted drive was encrypted and the source folder plain I could remove the 2nd copy part as follows:

Plain folder
V
BoxCryptor
V
SafeSync bidirectional sysnc with cloud.

The early versions of safesysnce could not workthis way as if Boxcryptor failed it would assume all the file on the drive had been deleted and delete them on the cloud sever.
They say they have now chnged this but I have not had chance to test it.
I hope this helps

Robert

Interesting suggestion about reversing the encryption direction!
