Influx_stress: 100x slower on Mac than on Linux

1

I installed InfluxDB 1.2.2 both on my newest MacBookPro (SDD) and on an older Linux box with HDD:

I see an average query response time on Mac with 354.167637ms vs 4.092117ms on Linux.

Factor 100 difference?

Where is this coming from?

@zopyx I would guess this would be because the writes are slower on your HDD machine and more data is coming back on the queries on the mac.

Why would a box with a HDD be 100 times faster than a SDD? Makes no sense.

@zopyx influx_stress works by querying the data it has just written. The writes are faster on your macbook this could be causing more data to be returned with each query. That could explain the discrepancy there.

I would also suggest that you look at our newer influx-stress for this kind of work.
