><br></div></div></blockquote><div>As Kim had mentioned I had loaded the CONFIG_CRYPTO_DEV_TALITOS as a module with the module in the kernel i am getting a lower throughput! I am getting only 13.4Mbps however without the module inserted i get 14.7Mbps how could this be possible and the results sounds really ridiculous to me! And when the CONFIG_CRYPTO_DEV_TALITOS is loaded i am able to view it using grep talitos /proc/interrupts. so the hardware accelerator is getting used however resulting in a lower throughput! That's absurd am I missing something here?</div>

<br></div></div></blockquote><div>I tried even with KLIPS and ocf,cryptodev and ocf-talitos and even here i get no better throughput its only 11.7Mbps! Why am I getting such a lower throughputs?</div><div>Thank you so much everybody for helping out. Awaiting your replies to proceed further.</div>

</div></div>Yeah, Kim wrote the driver, but the in kernel one is more up to date ;-)<br>
