I don't think this is a repeat post, but in case some of you didn't share. HOnza has been running some benchmarks of hosting on various platforms. I did the tests back in Dec. You can see the full results here: BenchTest - Test FileMaker Performance | 24U Software
My personal experience was that I'm not sure where Claris hosting is, but even controlling for distance, the Filemaker hosting is SUPER slow (higher numbers are better)
I’m 540 miles from the Amazon Servers and 909 miles from Chicago according to Apple Maps (so not as the crow flies) FWIW… I’m not sure where their “west” server is located, but I’m 1,895 miles from Denver, and roughly 2,900 from LA or Seattle or San Fran.
