Hi,
I noticed that anti-virus software slow down the open().
I stopped the anti-virus software and re-run the test.
(Average of 10 times)
master: 1924tps
Hold_xlogreader.patch: 1993tps (+3.5%)
Read_from_walbuffer.patch: 1954tps(+1.5%)
Therefore, the effect of my patch is limited.
I'm sorry for the confusion.
Regards,
Ryohei Takahashi
