Hey everyone. Here's a question that may have been answered in the past, but I'm not real satisfied with what I've found on Google.
I have been tasked with setting up a reverse proxy (open source, probably squid) that is capable of handling 5000 requests per second or more. Yes, 5000/sec. It's a world gone mad, I tell you. Licensed products like iMimic and Volera are not options. The OS is flexible (I'm leaning toward a recent 4.x version of FreeBSD) and the hardware is limited to what's on hand - either a Dell 2550 or 2650 with 1G Ram, 30G hard drive space, and varied CPU configurations. What we have available are as follows: single 933MHz Xeon in the 2550, single or dual 1.3 or 1.8 GHz Xeon in the 2650. I realize that Squid relies more on disk seek times than actual transfer rate or CPU power. If I've been told right, the disks are all mirrored 30G drives, but I don't have seek times on hand. I know that most reverse proxies out there - both commercial and open source are typically single CPU architectures, so that will be the initial focus. The problem I would like help with here is the version of FreeBSD that would be more likely to handle this kind of load, particularly with respect to Posix asynchronous I/O. I've been told that 4.6 and earlier didn't have great Posix A-I/O support, but is it better in 4.8, or should I jump to 5.0? Also, if anyone knows of a reverse proxy that may be able to do better than Squid, I'd certainly welcome the suggestion. The benchmarks I've seen online indicate I may need to improve squid by a factor of 10. Not sure that's really an option unless the benchmark I've seen is horribly biased. Of course, if anyone has a web site that details some of the finer tweaks that might at least get Squid close to the requirements, that'd be great too. Thanks in advance.
