Elasticsearch Performance Tuning

Practical techniques for tuning indexing throughput, query latency, and resource usage in Elasticsearch.

Kafka Performance Tuning

Practical tuning levers on the producer, consumer, and broker sides for maximizing Kafka throughput and minimizing latency.

What is CPU Scheduling?

CPU scheduling is the OS mechanism that decides which ready process or thread gets to run on the CPU next, aiming to balance throughput, fairness, and responsi…

What Is Round Robin Scheduling?

Round robin scheduling is a preemptive CPU scheduling algorithm that gives every process a fixed time slice, called a quantum, in a cyclic order, so no single…

CPU-Bound vs I/O-Bound Processes: What Is the Difference?

A CPU-bound process spends most of its time performing computation and rarely blocks, while an I/O-bound process spends most of its time waiting on disk, netwo…

What is FCFS Disk Scheduling?

First-Come-First-Served (FCFS) disk scheduling services disk I/O requests in the exact order they arrive in the queue, moving the disk head to each requested c…

What is Throughput in Operating Systems?

Throughput in an operating system is the number of processes completed per unit of time, and it measures overall system productivity rather than how any single…

What are I/O Scheduling Strategies?

I/O scheduling strategies are the algorithms an OS uses to order pending disk requests so as to minimize seek time and maximize throughput, with FCFS, SSTF, SC…

What is Latency vs Bandwidth?

Latency is the time it takes a single piece of data to travel from sender to receiver, while bandwidth is the maximum volume of data that can move through a co…

What is the Nagle Algorithm and When Should You Disable It?

Nagle’s algorithm is a TCP send-side optimization that buffers small outgoing segments and coalesces them into one larger segment instead of firing off many ti…

Bandwidth vs Throughput: What is the Difference?

Bandwidth is the theoretical maximum data rate a link can carry, usually stated in bits per second, while throughput is the actual data rate achieved in practi…

What is Little’s Law and How Do You Apply It?

Little’s Law states that the average number of requests in a system (L) equals the average arrival rate (lambda) multiplied by the average time each request sp…

Latency vs Throughput: What Is the Trade-off?

Latency is the time a single request takes from start to finish, while throughput is the number of requests a system completes per unit of time, and optimizing…
