API Performance: When Every Millisecond Counts

api performance from apimetrics

Admittedly, it was a slow week in terms of API performance problems. Things are mostly working as they should, with the exceptions below among others. But the issues we did see highlight just how crucial it is to be on top of API performance with proper monitoring, observation, and validation. Let’s take a look.

Top Drops in API Performance

Kraken in the Crypto Exchanges collection dropped 13 places, the most of any drop in any collection last week. This was primarily due to a slight but steady increase in processing time affecting most monitored endpoints.

This may seem dramatic, and to be sure, anytime you have an API performance issue, it’s going to impact a business in terms of time, money and customer lost. But there’s only a .57 CASC score difference between the first-place Coin Metrics and 16th place Kraken. When everyone is performing well, even the slightest stumble can knock you out of the game.
Ulster Bank API performance

Ulster Bank NI in the Open Banking UK Production collection dropped 10 places.

This was due to a partial outage on the 14th affecting their Create Consents endpoint which saw their API return HTTP 500 Internal Server Error responses.

Department of Energy API Performance

Once again, the Department of Energy in the US Government collection was in the Red Zone with a CASC score of 3.67. Still terrible, but improving. Outlier rate is down 0.99% points now sitting at 35.7% and standard deviation is down 7.31% to 3984ms.

It’s clear they just don’t care about this API, or their API performance in general.
