Hello all,
Did anyone use SyncDocs to sync or backup more then 150K files? I wanted to know how much the SyncDocs program take in memory and CPU consumption to know if to buy storage place from google...
Until now I used SpiderOak,SugarSync,SafeSync and they good BUT they consume more then 300Mb-400Mb of memory and SpiderOak eat lots of CPUs usage.
Thanks!!

Hi,
Syncdocs can sync more than 150K files, but will also consume memory, as the sync data is cached in memory.

Thanks Andrew, but how much memory? do you sync more then 10K? how much memory SyncDocs consume?

I'm curently resyncing 75K files (7GB). right now it uses about 200MB in memory and I remember it peaking at about 400MB. That doesn't bother me most, though.
Processing the querried results eats up quite some cpu resources - roughly 50-75% of one to two core i5-760 cpu cores.
In my opinion, the biggest bottleneck is that 3 secound round trip time to a google server an back. Completing one sync cycle with no changes on both sides takes more than an hour to complete. Even with a cable broadband connection and 2 Gbit of upload bandwith, initial upload of 7 GB took 75 hours. But thats due to the google apps api limitations of one connection at a time only, I guess.

Its a .net app, so the memory management is handled by .net, so it cleans up memory when it needs it. We've recently put in a lot of work to reduce the memory consumption, but each record file takes about 700bytes.
Our next big task on the Syncdocs roadmap is to improve the speed and latency.
Dan is exactly right in pinpointing the bottleneck.
