Pinning is very slow with js-datastore-s3


I am using IPFS with js-datastore-s3. However, when I try to pin a large number of files(about 1,000 files and 200MB) with pin.addAll, the speed will slow down dramatically. Six hours later, it was not over. It will take only 2 minutes without js-datastore-s3. Is there any solution to this problem?
