Re: Relation extension scalability

1. Relation Size : No change in size, its same as base and v13

2. INSERT 1028 Byte 1000 tuple performance

-----------------------------------------------------------

Client base v13 v15

1 117 124 122

2 111 126 123

4 51 128 125

8 43 149 135

16 40 217 147

32 35 263 141

3. COPY 10000 Tuple performance.

----------------------------------------------

Client base v13 v15

1 118 147 155

2 217 276 273

4 210 421 457

8 166 630 643

16 145 813 595

32 124 985 598

Conclusion:

---------------

1. I think v15 is solving the problem exist with v13 and performance is significantly high compared to base, and relation size is also stable, So IMHO V15 is winner over other solution, what other thinks ?

2. And no point in thinking that V13 is better than V15 because, V13 has bug of sometime extending more than expected pages and that is uncontrolled and same can be the reason also of v13 performing better.
