Block storage and object storage performance limits on 3Engines Cloud🔗

On 3Engines Cloud, there are performance limits for HDD, NVMe (SSD), and Object Storage to ensure stable operation and protect against accidental DDoS attacks.

Current limits🔗

Block HDD
500 IOPS (read and write)
Block SSD/NVMe

3000 IOPS (read and write)

NOTE: On 3Engines Cloud, all SSD storage is NVMe-based.

S3 Object Storage (General Tier)

2000 operations per second with a

  • 2500 burst limit per bucket and
  • 150 MB/s transfer per request

In majority of cases, the actual throughput may be larger because:

  • Typical downloads use multiple requests and
  • More than 99.95% of requests stay below 100 MB/s.

Again, this limit primarily helps mitigate accidental DDoS scenarios.
