amazon ec2 - EC2 performance inconsistancy? -

-

we launched large 64-bit instance , performance severely lacking. commands ls, less, , cat take absurd amount of time, 10 seconds. top revealed load on 2 when in fact nothing running on our shell, @ least nothing had run.

when launched second instance, performance quick expected. wondering if other people have experienced type of performance variance. how occur? exploring using ec2 compute cluster , variance quite inconvenient if happens often.

yes, i've experienced couple of times - 2 or 3 times @ least.

we open threads on aws support forum , response. i'm not sure how aws monitors forums, etc. think unless don't report issues, don't fixed.

the usual fix terminate instance , launch another.
