Hello.
I have problem with encryption and decryption speed using Kleopatra - it takes more than 10 seconds to encrypt or decrypt file of 100MB in size. Thta means performance aound 10MB/s or less ehich is really slow. More info:
- tested on 2 computers with newest GPG4Win and newest W10 (one i5 16GB RAM and SSD, other i3 8GB RAM SSD) - the same slow performance around 10MB/s
- encrypting with GPG under Cygwin on those computers is instant so 100MB/s or more
- tested on Linux machine - performance around 100MB/s with Twofish and 200MB/s with AES256 tested with bigger files
- my config file disables compression
- encrypted data are test text file filled with “a” letter to double chck if the file is not compresssed before encrypting
- tested with symmetric encryption and asymmetric ed25519 and RSA keys, with Twofish and AES
- creating 4096 bit RSA key does not take long - there is no problem with insufficient random data
What can be the cause? Is it standard performance for Windows version? Why Cygwin performance is much better. Can somebody compare my results?
