Read Plus May 2022
From Linux NFS
The following is performance test results for the proposed NFS v4.2 READ_PLUS patches submitted to the list in May 2022. I collected data using both physical Netapp lab machines and virtual machines on my laptop to get a complete picture of how the new code will impact performance. The test I ran created large files with various sizes of HOLEs on the server and read them back on the client. I used the vmtouch utility to directly place or evict the test files from the server's cache to collect data on the cases where the server has the files already cached or not.
Tests were performed using the v5.18-rc6 kernel as a baseline, and then the proposed patches were applied on top (first server changes, then client changes). The following files were tested:
| File | Description |
|---|---|
| $SIZE-data | Test file containing entirely allocated data |
| $SIZE-hole | Test file that is entirely a sparse hole |
| $SIZE-mixed-1d | Test file that alternates hole and data segments every other page, beginning with data |
| $SIZE-mixed-1h | Test file that alternates hole and data segments every other page, beginning with hole |
| $SIZE-mixed-2d | Test file that alternates hole and data segments every two pages, beginning with data |
| $SIZE-mixed-2h | Test file that alternates hole and data segments every two pages, beginning with hole |
| $SIZE-mixed-4d | Test file that alternates hole and data segments every four pages, beginning with data |
| $SIZE-mixed-4h | Test file that alternates hole and data segments every four pages, beginning with hole |
| $SIZE-mixed-8d | Test file that alternates hole and data segments every eight pages, beginning with data |
| $SIZE-mixed-8h | Test file that alternates hole and data segments every eight pages, beginning with hole |
| $SIZE-mixed-16d | Test file that alternates hole and data segments every sixteen pages, beginning with data |
| $SIZE-mixed-16h | Test file that alternates hole and data segments every sixteen pages, beginning with hole |
