I upgraded from Meteor 1.8 to 1.11. I’m facing one issue. A particular activity runs very slowly on my production server if I use node v12.18.3 on production. But this activity runs properly on development machine. Also on production machine if instead I use node v12.0.0, this activity runs properly.
I believe meteor 1.11 uses node v12.18.3, so why I’m facing this issue?
As regards the activity, it open 200 ssh connection to different machines in my network and extracts data from them. I use async.parallelLimit to carry out 200 operations in parallel. When I use node v12.18.3 on production machine, when this activity is going I can see node process hogging 100% CPU continuously. But with node v12.0.0, CPU crosses 100% for a very small time.
Any idea what could be wrong?
