[#2492][FOLLOWUP] improvement: change the default value of
chunkPoolCapacityRatio (#2554)
### What changes were proposed in this pull request?
Change the default value of chunkPoolCapacityRatio

The proportion and the frequency of small blocks is not high. If this value
is set too high, it may cause off-heap memory overflow.
Fix: #2492
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Verify in production environment.
