   >From where do you get this 2-5% improvements number ?
   
   That is an estimation.
   Your measurements show that the peak throughput is ~1-2M ops/sec.
   
   That means a single write takes ~0.5..1microsecond (== 1sec / 1Mops/sec).
   A real-life HTTP test would probably top at 10-50K/sec which is 20..100 microseconds per
test.
   If the improvement cuts 0.5 microseconds from each write, then the improvement for HTTP
would be like (20...100us => 19.5..99.5us) which is 10..51K ops/sec.
