To summarize for any encrypted object there exists (at least) three different keys:

- [OEK](#oek): A secret and unique key used to encrypted the object, stored in an encrypted form as part of the object metadata and only loaded to RAM in plaintext during en/decrypting the object.
- [KEK](#kek): A secret and unique key used to en/decrypt the OEK and never stored anywhere. It is(re-)generated whenever en/decrypting an object using an external secret key and public parameters.

Безусловно, на этом же сервере будут работать и **другие процессы**, которые не относятся к вашему приложению.

Интересная деталь заключается в том, что процент **использования центрального процессора (CPU)** каждым процессом может сильно меняться с течением времени, но объём занимаемой **оперативной памяти (RAM)** остаётся относительно **стабильным**.

	// TLDR..
	// Not used anymore xl.meta captures the right blockSize
	// so blockSizeV2 should be used for all future purposes.
	// this value is kept here to calculate the max API
	// requests based on RAM size for existing content.
	blockSizeV1 = 10 * humanize.MiByte

	// Block size used in erasure coding version 2.
	blockSizeV2 = 1 * humanize.MiByte

	// Buckets meta prefix.
	bucketMetaPrefix = "buckets"

}

Esse "esperar por algo" normalmente se refere a operações <abbr title="Entrada e Saída">I/O</abbr> que são relativamente "lentas" (comparadas a velocidade do processador e da memória RAM), como esperar por:

* dados do cliente para serem enviados através da rede
* dados enviados pelo seu programa para serem recebidos pelo clente através da rede
