The download is done synchronously, that is, it downloads one content, then the other, the other and so on. The comparative table shows the processing behavior:
| # | Download in milliseconds | Bytes | Average time (ms) |
|---|---|---|---|
| 1 | 8847 | 1993391 | Not considered because the first time it runs, it's always slow |
| 2 | 5489 | 1988665 | 5489 |
| 3 | 6136 | 1988483 | 5812 |
| 4 | 5747 | 1988630 | 5790 |
| 5 | 5658 | 1986383 | 5757 |
| 6 | 6335 | 1993106 | 5873 |
| 7 | 5713 | 1989936 | 5846 |
| AVERAGE TOTAL | 1989200 | 5761 |
The download is done synchronously and in parallel, that is, each download is a task that is triggered almost simultaneously. The comparative table shows the processing behavior:
| # | Download in milliseconds | Bytes | Average time (ms) |
|---|---|---|---|
| 1 | 3668 | 1988630 | Not considered because the first time it runs, it's always slow |
| 2 | 2351 | 1993473 | 2351 |
| 3 | 2393 | 1990277 | 2372 |
| 4 | 2300 | 1995308 | 2348 |
| 5 | 2215 | 1987888 | 2314 |
| 6 | 1611 | 1961855 | 2174 |
| 7 | 2495 | 1989507 | 2227 |
| AVERAGE TOTAL | 1986384 | 2820 |
The download is done asynchronously, that is, the contents are downloaded almost simultaneously. The comparative table shows the processing behavior:
| # | Download in milliseconds | Bytes | Average time (ms) |
|---|---|---|---|
| 1 | 8353 | 1965105 | Not considered because the first time it runs, it's always slow |
| 2 | 6258 | 1965301 | 6258 |
| 3 | 5811 | 1963942 | 6034 |
| 4 | 6161 | 1962471 | 6076 |
| 5 | 5871 | 1964627 | 6025 |
| 6 | 5785 | 1968559 | 5977 |
| 7 | 5873 | 1962744 | 5959 |
| AVERAGE TOTAL | 1964607 | 6055 |
The download is done in an asynchronous and parallel way, that is, the contents are downloaded almost simultaneously. The comparative table shows the processing behavior:
