we operate for our customer a server with a single mongo instance, gradle, postgres and nginx ruing on it. The problem is we had massiv performance problmes until mongodump is ruing. The mongo queue is growing and no data be queried. The next problem is the costumer want not invest in a replica-set or a software update (mongod 3.x).
Has somebody any idea how i clould improve the performance.
command to create the dump:
mongodump -u ${MONGO_USER} -p ${MONGO_PASSWORD} -o ${MONGO_DUMP_DIR} -d ${MONGO_DATABASE} --authenticationDatabase ${MONGO_DATABASE} > /backup/logs/mongobackup.log
tar cjf ${ZIPPED_FILENAME} ${MONGO_DUMP_DIR}
System: 6 Cores 36 GB RAM 1TB SATA HDD + 2TB (backup NAS)
MongoDB 2.6.7
Thanks
Best regards, Markus
