Plan tiers are usually sorted by RAM, which is the least informative number on a spec sheet for most buyers. Two plans with 2 GB of memory can differ by a factor of three in CPU allowance, disk throughput and transfer, and the tier labels (Starter, Plus, Pro) tell you nothing about which one your workload needs. Decoding the sheet is a matter of translating each number into a workload property, and comparing the budget VPS plans<\/a> with that translation in hand.<\/p>\n\n\n\n

vCPU Count Is a Share, Not a Core<\/h2>\n\n\n\n

A plan advertising 2 vCPU on a shared host is allocating two threads of a contended physical core, usually with a fair-use ceiling. The number that matters is the sustained performance of those threads under load, which is why providers that publish a CPU model and a steal-time ceiling are worth more than providers that publish a core count.<\/p>\n\n\n\n

For sizing purposes, treat a shared vCPU as roughly 60% to 80% of a dedicated core for sustained work, and as a full core for bursty traffic served from cache. That single adjustment explains most of the gap between advertised and actual capacity on entry-level plans.<\/p>\n\n\n\n

RAM: The Number That Decides Your Stack<\/h2>\n\n\n\n

Memory determines what you can run concurrently, not how fast any single thing runs. A 1 GB plan runs a single PHP-FPM pool and a small database if you keep workers low. A 2 GB plan runs the same stack with a comfortable page-cache margin. A 4 GB plan starts to support containerized services without swap pressure.<\/p>\n\n\n\n

Disk: Capacity, Type and the Number Nobody Prints<\/h2>\n\n\n\n

Capacity is the easy part. Storage type matters more: SATA SSD, NVMe, and network block storage differ by an order of magnitude in random IOPS, which is what databases and package installs actually consume. A 40 GB NVMe plan beats a 100 GB SATA plan for almost every web workload. A nominal 300 MB\/s sequential figure says nothing about the 4K random reads that a MariaDB or PostgreSQL query path depends on.<\/p>\n\n\n\n

The missing number is the IOPS floor. Budget providers share an array across dozens of tenants, so peak-hour throughput can collapse even when space is plentiful. Expect 3,000 to 8,000 random 4K IOPS on entry NVMe tiers and 500 to 1,500 on shared SATA; if a provider publishes a per-plan IOPS guarantee, that line is worth more than an extra 50 GB of space.<\/p>\n\n\n\n

Bandwidth: Allowance Versus Port Speed<\/h2>\n\n\n\n

A 4 TB allowance on a 100 Mbit port is a different product from a 2 TB allowance on a 1 Gbit port. The allowance caps monthly volume; the port caps instantaneous throughput. Serving a 2 MB page to 50 concurrent visitors needs about 800 Mbit, which no allowance will help you reach if the port is capped at 100.<\/p>\n\n\n\n

For most small sites, 1 TB on a 1 Gbit port is better than 4 TB on 100 Mbit. The exception is file distribution and backup targets, where monthly volume dominates and burst throughput is irrelevant. Estimate the page weight first: a 300 KB page served 30,000 times a month is roughly 9 GB of transfer, which means bandwidth is rarely the constraint for text and image sites and almost always the constraint for media.<\/p>\n\n\n\n
