Furthermore, the sys time in 2.2.20 was about 45% of the total time (55 %
user time), in 2.3.7 is about 38 %. I noticed the difference is
probably due to the table/record locks that are always written to a file
and this could force the double buffer/cache copy everytime a table is
accesed.
Congratulations, the results look very good.
My question is, are the changes going to be back ported to 2.2.x?
My second question is, can a 4096 bytes block size improve results even
more?
Best regards.
PS: the machine was a PII Dual 300 MHz, 512 MB RAM (more than 400 MB of
buffer-cache), with Adaptec 7880 and two 8 GB disks.
