mongodb insert slow – collection mongodb

Insert 200+ million rows into MongoDB in minutes

 · Reading the displayed log of mongoimport, I realised that the insertion time is really slow and it would take around 6-7 hours to import the entire data, Hence, I cancelled the import process and started the optimization phase which I will explain in the next section, Notes: MongoDB daemon process was running with default configurations

 · when inserting with write concert different than ERRORS_IGNORED inserting into database is incredibly slow – 100 inserts takes more than 5 seconds on localhost With write concern set to ERRORS_IGNORED this takes less than 300ms Naturally one should expect lower speed with higher write concern; however experiments in mongo console shows, that the difference is much, much more subtle,

 · Avoiding slow insert performance with MongoDB 2,6 shell #mongodb With the 2,6 release of MongoDB the default shell behavior has changed Previously with 2,4 and below, a quick-and-dirty for loop to insert 100,000 records would have only checked the status of the last operation in the loop, This is fast, but not exactly what you would like

intermittent slow inserts with WiredTiger b-tree

 · During the initial insertion of the records such as the quick insertions of the least populated and obscure TLDs and initial ,com etc insertion , I get decent insert speeds of about 10k-15k inserts per second, However, this slows to a crawl, partway through, Since MongoDB uses a B-tree for indexing primaries, shouldn’t the performance slowdown due to database size be minimal?

Avoiding slow insert performance with MongoDB 26 shell

I get intermittent slow inserts with the WiredTiger b-tree in 2,8,0rc2, These are the top-10 worst ones from a test in progress, The numbers are milliseconds, so there are many inserts that take more than 100 seconds: 119597 118610 118465 117977 117437 116611 116498 116068 113909 113342, This doesn’t reproduce with the WiredTiger LSM, I wonder if a slow checkpoint is the problem but I have not done the work to trigger …

Decreasing the period between journal commits will increase the number of write operations which can limit MongoDB’s capacity for write operations Increasing the amount of time between journal commits may decrease the total number of write operation but also increases the chance that the journal will not record a write operation in the event of a failure,
