RE: Speed up COMMIT PREPARED

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.

I noticed that the previous Read_from_walbuffer.patch has a mistake in 
xlogreader.c.
Could you please use the attached v2 patch?

The performance result of the previous mail is the result of v2 patch.
