Thanks. Will have a look soon. |
The read buffer won't rotate data if it can be increased without allocating
more memory. The table below compares the performance before and after the
changes
| time(s) | %usr | %sys | %CPU | rotation
------|---------| ------|------|-------|------------
Eager | 92.22 | 67.37 | 2.92 | 70.29 | 6.7 Gbps
Lazy | 91.16 | 60.15 | 2.82 | 62.97 | 99.0 kbps
The biggest gain in the benchmark above is in CPU usage because the overall
time cannot be decreased much since the client is far from saturating the CPU.
