2.2.2. Performance Improvements¶
Substantial improvements in measured packet throughput have been observed in a number of CSIT rls1710 tests listed below, with relative increase of double-digit percentage points. Relative improvements for this release are calculated against the test results listed in CSIT rls1704 report. The comparison is calculated between the mean values based on collected and archived test results’ samples for involved VPP releases. Standard deviation has been also listed for CSIT rls1710. Performance numbers since release VPP-16.09 are provided for reference.

2.2.4. Known Issues¶
Here is the list of known issues in CSIT rls1710 for VPP performance tests:
| # | Issue | Jira ID | Description |
| 1 | Vic1385 and Vic1227 low performance. | VPP-664 | Low NDR performance. |
| 2 | Sporadic NDR discovery test failures on x520. | CSIT-750 | Suspected issue with HW settings (BIOS, FW) in LF infrastructure. Issue can’t be replicated outside LF. |
| 3 | VPP in 2t2c setups - large variation of discovered NDR throughput values across multiple test runs with xl710 and x710 NICs. | CSIT-568 | Suspected NIC firmware or DPDK driver issue affecting NDR throughput. Applies to XL710 and X710 NICs, x520 NICs are fine. |
| 4 | Lower than expected NDR throughput with xl710 and x710 NICs, compared to x520 NICs. | CSIT-569 | Suspected NIC firmware or DPDK driver issue affecting NDR and PDR throughput. Applies to XL710 and X710 NICs. |
