Re: [edk2] [PATCH v2] ShellPkg/TftpDynamicCommand: Change file writing method in tftp
Hi Laszlo, Thank you for the comments. For your questions below: > Before the patch, the shell would write the entire file in "one go". > > In this particular case, I'm not interested in the memory allocation > size, but the transfer block size that the shell would ultimately use > with EFI_FILE_WRITE. I find it interesting because some lower-level > storage drivers may have limitations themselves (for example, a single > SCSI transfer might not be larger than 1GB). What layer would handle > (split) a downloaded file larger than that into smaller chunks? Maybe > the FS (FAT) driver? Although underlying driver can handle split writing, we still need split writing in application layer because: 1. To improve user experiences -- if write the entire file in "one go" way, the shell looks like hanged after download finished. After this patch, shell prompt will show up immediately after the downloading progress bar finished. 2. Before this patch, if the file size is larger than physical memory size, we cannot download the file. > And, after the patch, we're now writing TFTP packet-sized chunks to the > file. Is this not a performance problem for traditional spindle disks > ("spinning rust")? If neither the rest of the driver stack, nor the disk > controller itself, support some form of write caching, then writing out > every TFTP packet in isolation (especially for a multi-GB file) could be > detrimental to performance (and maybe to the health of the spindle disk). > > Currently I'm not affected by this use case either way, so feel free to > ignore, but it might make sense to implement some larger chunking here, > like 64KB or 128KB -- later, as a separate Feature BZ. We agree with this comment. It is a performance problem and will be fixed.
