int, byte = 4 byte both you stupid noob, you wont save memory if you use bytes, you only limit the values.

 

hehe i like guys like you.

 

if you use it for an average declaration where its a number value with a getter and setter yes it dont make any difference BUT if you use it where you handle it as an int array or a key or value or a data holder it really makes a difference after some time.

 

Just so you understand it lets say i optimize from that point of view the l2skill of l2jserver after i finish with it i see -5mb memory footprint and i did it with 1 single class now multiple with the number of places where it can be done.

Smart boy ;) I thought you wouldnt know that and fall in the trap we setup :)

i see you write something long so lets put some math into play.

 

the sizes are:

byte: 1 byte

short: 2 byte

int: 4 byte

long: 8 byte

 

if we have an array which have 100 value the size of it in allocated memory as follows.

 

primitiveType[] array = new primitiveType[100];

 

so since the array takes 12 byte as a header the calc is:

 

12(header)+100(size)*primitiveType(which can be any datatype listed above).

 

so in that case the allocated memory for each looks like that:

 

byte = 112

short = 212

int = 412

long = 812

So according to your estimations, how much do you think you can reduce the average memory usage ( % ) ? Can you get it down to -50% ? How many human-work-hours do you think this will take ? And how are you going to keep updating a pack along with 2-3 other devs, when the competitors ( l2j / l2jfree ) have at least 10 developers coding ?

-50 no but it can save up 25-30mb from memory footprint(at startup) as far as my experimenting goes with l2j so its still good.

    • ## [1.4.0] - 2026-01-28   ### ✨ New Features - **Vote System**: Lineage 2 servers can now use our vote–reward system. Players vote on the website and claim rewards in-game (1 vote = 1 claim) - **Vote Page**: On each server’s page (`/servers/<server>`), a **“Vote for Server”** button opens a dedicated vote page with cooldown info and optional Turnstile verification - **By Votes View**: The **“By Votes”** tab on the main page shows **actual vote counts** per server - **API Documentation**: New **API Docs** page at `/docs` (and footer link) with HMAC auth, endpoints, and examples for game server integration - **Vote API (My Servers)**: Server owners can open **“Vote API”** in My Servers to manage credentials, cooldown, allowed IPs, and open the docs   ### 🔄 Improvements - **Server Pages**: Single-server data is cached and loads faster; server pages can be opened by ID or by name (e.g. `/servers/my-server-name`) - **API Root**: Visiting the API root redirects to the docs URL configured in admin (default: site docs page) - **Admin Panel**: New **“Vote System”** tab for global settings (Turnstile, API security, default cooldown, docs URL)   ### 🔐 Security & Reliability - Turnstile (CAPTCHA) support for vote submissions to reduce abuse - HMAC-protected game server API for secure vote check/claim and stats
