Hello, Recently, I experienced softCommits taking up to 30 seconds to return. The application in question was creating a document per interaction and doing a soft commit at the end of the interaction. After a period of a few dozens clients sending a continuous stream of such interactions, I could see it getting slower and slower and the source appears to be the softCommit.
No changes in the XML config have been provided in terms of commit timings. The JVM is given 20GB heap space, of which it seems to hang steady at 10GB at all times throughout usage, and there's some 25M documents getting up to a total of 150GB of data on disk. Everything is on 1 shard, with 2 hosts each having 1 instance of the collection. The underlying disk is an SSD on both hosts. Before I dive into documentation or code, I was wondering if anyone here might have immediate ideas of what could cause such behavior for soft commits. If someone has an immediate bit of knowledge towards what causes softCommits to take up to 30 seconds, that'd be appreciated. Regards, Koen De Groote
