Follow | Faster Amazon S3 File TransfersWhy CS Browser Pro Transfers Files FasterCS Browser Pro can run many uploads and downloads in parallel, while the Free version is limited to two concurrent uploads and two concurrent downloads. This additional parallelism can significantly reduce the total transfer time, especially when transferring large batches of small files or using multipart transfers. The level of concurrency is configurable, allowing CS Browser Pro to make efficient use of fast network connections and adapt to different workloads. Transferring Many Small FilesPro VersionWith CS Browser Pro, multiple files can be uploaded or downloaded at the same time. A large batch does not have to wait behind only one or two active transfers. More parallel transfers mean less waiting. They also help make better use of a fast network connection. ![]() Free VersionCS Browser Free is limited to two concurrent uploads and two concurrent downloads. On high-latency connections, two active requests may leave much of the available bandwidth unused. ![]() Large Files and Multipart TransfersAmazon S3 multipart upload splits a large file into parts that can be transferred independently and in parallel. If one part fails, only that part needs to be retried. CS Browser enables multipart uploads and downloads by default. The default part size is 100 MB and can be changed in Tools > Options > General. CS Browser Pro processes multiple file parts in parallel, while the Free version is limited to two upload or download threads. On fast connections, additional parallelism can considerably reduce transfer time for large files. Pro VersionMultiple parts are uploaded or downloaded simultaneously, allowing CS Browser Pro to keep more of the available bandwidth in use. ![]() Free VersionOnly two parts can be uploaded or downloaded concurrently. Additional parts remain queued until one of the active transfers finishes. ![]() Configure Concurrent TransfersOpen Tools > Options > Queueing. ![]() Set the maximum numbers of concurrent uploads and downloads, then click Save Changes. ![]() Higher values can improve throughput on fast, high-latency connections, but excessive concurrency may reduce performance. Adjust the values to suit your network, storage service and hardware. | CS Browser 13.5.5 Freeware ![]() Social Connection Our customers say "CS Browser is an invaluable tool to me as a web developer to easily manage my automated site backups" -Bob Kraft, Web Developer "Just want to show my appreciation for a wonderful product.
