LiteLoader very slow using encrypted DB

Hello.

When using LiteLoader with an encrypted database data loading is very slow.

I changed the encryption algorithm and "page_size" and the results are the same.

Using the database without encryption speed is very good.

I'm using Delphi 7 and LiteDAC 1.5 trial.

Thank you.

hello,

We checked the LiteLoader performance on an encrypted DB, and the performance crash on an encrypted DB is not heigher than 15%, this is due to the fact that the process of encryption/decryption takes some time.
We have performed re-factoring of the data loading process using TLiteLoader, and the data loading speed will be increased significantly.

Thank you.

Could you give me any estimation on when the next LiteDAC build might be released?
