Subject: a problem of long STW because of GC ref-proc


Yes,it will be remission by your advise,but there only get request in our business,so 16KB is better.
IMO,the locks of offset will always be used,so is the strong reference a better choice?

主题: Re: a problem of long STW because of GC ref-proc

Seems your block size is very small (16KB), so there will be
70*1024*1024/16=4587520 block (at most) in your BucketCache.
For each block, the RS will maintain a soft reference idLock and a
BucketEntry in its bucket cache.  So maybe you can try to
enlarge the block size ?
