Re^2: Mixing sysread() with <FILEHANDLE>?

I would definitely not use the FTP model. It just brings in too many operational issues (firewalling, security, etc.) Moreover, you have to make a separate TCP connection for each 'blob', and that will easily eliminate any speed-up gained by not having to encode the data.

Security and firewalls are a concern for all TCP/IP communication; FTP isn't secure, but that's not relevant here. Given the use of SSH, SFTP could be used, which should add no security concerns. As for using FTP as a model, the key point is having a different session for the binary data. As for performance, I don't think you can assume that a new session per blob is going to be a major factor. It depends on the average size of those blobs. Anyway, as the original poster noted, a single separate data session would likely serve his purpose. sas	[reply]
