 ### Linux read throughput  
 
-The following graphs compare sequential reads of ~3,500 MiB/s reads with `nconnect`, which is roughly 2.3X non-`nconnect`.

 ### Linux write throughput  
 
-The following graphs show sequential writes. They indicate that nconnect has no noticeable benefit for sequential writes. 1,500 MiB/s is roughly both the upper limit for the sequential write and the egress limit for D32s_v3 instance.
