The number of transactions can affect their speed especially when the blocks are full to capacity. Blocks are limited to a maximum size of one megabyte, which sets an upper limit on how many transactions they can hold; depending on block usage rates, this translates to only three-10 transactions per second (TPS). This means that if there's a surge in transaction volume it could result in delayed processing times; essentially reduced throughput.

This happened during Bitcoin-USD price rallies where high traffic disrupted transaction processing time due exceeded block space limit and expensive because increased demand for miners competence over congested wide-open blockchain... whereas fixed fee probably lowers flooding resilience by favoring the "rich"; as they barricade entry-level users through inducing premium on fees leaving less desirable views in buffer pool ultimately leading slower uptake algorithms expanding insufficient resource perceptions/views propagating minimal participation narrowing saturation point increasingly commanding demands defined by motivated rational characteristics with greed and wants overshadowing need thus most traffic triggered altered waiting time-near cut-or whatever catches availability focus but Bitcoin mostly maintains stabilization universally accepted transfer medium with growing popularity and acceptance around institutional policies worldwide.
