[Opendnssec-user] DNSSEC GPU acceleration of RSA sign operation

I implemented RSA 2048 batch decryption on NVIDIA GPUs in C/CUDA.
I would like to have some insight on the possible use of my code to speed up DNSSEC sign operations with RSA.
I do not have precise figures at hand right now, but the latency of my software depending on the GPU and the configuration of the CUDA execution is of hundreds of milliseconds (let's say 400 ms) and then number
of messages signed is up to 10 thousand.
Do you think that a high throughput batch decryption routine could be of any use in DNSSEC?
