Hi exports,

 

[Summary]
We have encountered a trouble that download of m2m table[sn_vul_m2m_entry_software] b/w CVE[sn_vul_entry] and CPE[sn_vul_software] is remarkably slow. If anyone has encountered the same problem, please share the solution.

 

[Environment]
Instance version: Utah
Plugins: Vulnerability Response Integration with NVD version 1.3.3

 

[Detailed]
We have started the DL of the m2m table[sn_vul_m2m_entry_software] 12 days ago, however, the number of imported records is 4M. So the throughput of DL should be 0.3M records/day. Since there are nearly 20M records in another environment where the downgrade has been completed, it would take nearly 60 days to continue downloading at this throughput, which is unacceptable.

 

[Supplement]
1. When we used ver 1.20 this download was completed in a few days and this is the first time I have encountered this problem using ver 1.3.3.
2. We have already implemented download acceleration using NIST's API Key, but it did not change significantly.

 

Best Regards,
