You’ll need to characterize what you’re seeing better than “multiple time slower” before it would be worth speculating on what’s going on.
We do not routinely test vpp when compiled w/ -DCLIB_VEC64. Can you describe the use-case which requires a main heap larger than 4gb? Thanks… Dave From: vpp-dev-boun...@lists.fd.io [mailto:vpp-dev-boun...@lists.fd.io] On Behalf Of Juan Salmon Sent: Sunday, May 7, 2017 7:31 AM To: vpp-dev@lists.fd.io Subject: [vpp-dev] vpp with 64 bit vec Hi, I compiled VPP with Dclib_vec64 option to have more than four Gigabyte heap size. It works correctly but multiple time slower than 32 bit version. It seems that inserting data in hash tables caused this problem. Is there any idea? Best Regards, Juan Salmon.
