Download speeds slow after upgrading to 1.5.8
I got exited and upgraded my server from 1.5.7 to 1.5.8 and ran into a few issues.
Download speeds became very very slow from different subnets/images/computer models. We usually get around 5GB/min on a bad day to 12GB/min on a good day. Look like we are capped at 2 - 2.8 GB/minute consistently now. Sometimes it went down to under a GB. However, uploading speeds remain the same which is over 5GB/minutes. I’ve tried different inits as suggested in here but it didn’t help.
This is not an issue but i’m curious. On the web UI at the login window it says Latest Version:1.5.7, Latest Development Version:126.96.36.199 and on FOG Configuration page says “You’re running the latest alpha-branch version: 188.8.131.528”. Should all be 1.5.8 or later?
@TaTa I am wondering if you have any news on this topic or if we can mark this solved.
@TaTa Have you done more testing on this? I am still stumped on the fact that it seems to only happen in UEFI mode.
On the web UI at the login window it says Latest Version:1.5.7, Latest Development Version:184.108.40.206 and on FOG Configuration page says “You’re running the latest alpha-branch version: 220.127.116.118”. Should all be 1.5.8 or later?
Sorry for that. There were some minor issues in the version checking on our webserver. Fixed that just now. Thanks for letting us know.
Ok, back to the issue. So turns out the slowdown is not between 1.5.7 and 1.5.8 but has been there with FOG 1.5.7 but only in UEFI mode. That an interesting one because at that stage I would expect there to be no real difference between UEFI and legacy boot. The Linux kernel uses a so call EFI stub for it to be loaded in UEFI mode but as far as I know should behave more or less the same after bootup either way. Sure there are differences like EFI VARs (
/sys/firmware/efi/efivars) only being accessible in UEFI mode but I would think that most drivers should not see the difference. Please make absolutely sure this is happening on the very same machine (not just same model) and confirm.
Legacy mode was at 11GB/m vs EUFI was at 2.2GB/m
OK just for clarity, you are getting the same uefi download speeds with Partclone 0.2.98 as with 0.3.13?
If so on what hardware (mfg and model)?
Have you tried this comparison with another model in uefi mode?
@george1421 Just tried a download using FOS 1.5.7 v0.2.89. Legacy mode was at 11GB/m vs EUFI was at 2.2GB/m
@TaTa Well it would be interesting to know if the older version of FOS Linux (in 1.5.7) changes your deployment rate. A few other forum members were getting 12GB/m with the 1.5.8 version of FOS Linux. I haven’t updated my production environment yet to 1.5.8, I’m getting 13GB/m+
@george1421 It is b0.3.13. It might not be partclone after all. I did some more tests. Downloading using UEFI mode is much slower than legacy mode. Legacy mode is at 6GB/minutes or more vs UEFI mode never go pass 2.8GB/minutes.
Upload speeds on both modes are about the same (5GB/min).
When you image a machined, when the partclone screen is on please confirm the version you see of partclone. It should b 0.3.13
If you are in a bind and need to image you can download the 1.5.7 version of FOS Linux here: https://fogproject.org/binaries1.5.7.zip (BUT I still need to know about the version of partclone!!) Extract bzImage and bzImage32 files and init.xz init_32.xz and overwrite the files in
This is an issue they devs were working on that delayed 1.5.8’s release. It should have been fixed with partclone 0.3.13
