Invasive Optimizations in All the Mods 10

Invasive Optimizations applies invasive optimizations to other mods, aiming to reduce server-side (tick) lag. This pack includes version 1.0.23, and it has been in the pack since 7.2 or earlier.^[1][2]

What it does

The patches are deliberately invasive. They change how other mods run internally, which makes them more likely to crash or break than a normal optimization mod. Each change can be toggled individually in the config, and the author says that is a good way to fix a problem temporarily while you wait for a fix.^[1]

The mod currently targets these mods: Accessories, Applied Energistics 2, Botany Pots, Create, Pastel, Pipez, Placebo, SFM and Xycraft Machines. Pipez gets the most patches, covering things like fullness checks, NBT comparisons and tag filter caching. Whether every one of these target mods is in this pack is not confirmed by the sources I have.^[1]

Some patches are marked experimental or of dubious usefulness, and the mod disables those by default. The SFM filter caching patch is one of them. It uses more memory and makes first compiles take longer. This pack's own settings for it are unverified.^[1]

Who it is for

It aims to reduce server-side tick lag in the other mods it patches, so it is most relevant when you run a server or a world using those mods.^[1]

Unverified I found no quests in this pack that involve Invasive Optimizations, and it does not appear on the ATM Star path. There is also no in-jar guidebook for it.

Good news: there's nothing to craft here. Invasive Optimizations is a server-side lag-reduction mod that patches other mods, so you don't need to make or collect anything to get its benefits.^[1]

The mod's own description says it makes invasive optimizations for other mods, aiming to reduce server-side (tick) lag. In this pack there are no quests for it and no in-pack recipes that produce its items, so there's no crafting path to follow.^[1]

What to do first

1. Play normally. The optimizations work in the background, so there's no setup step you need to complete.^[1]
2. If something breaks or crashes, disable this mod first. The author warns that the changes are invasive, which makes them more likely to crash or otherwise break.^[1]
3. Each change can also be toggled individually in the config. That's the quickest way to work around a problem while you wait for a fix.^[1]
4. If you find a bug, report it to the mod's issue tracker. The author says they will try to respond in a timely manner.^[1]

Which mods does it touch?

The project page lists optimizations for Accessories, Applied Energistics 2, Botany Pots, Create, Pastel, Pipez, Placebo, SFM and Xycraft Machines. If you're troubleshooting lag or a crash involving one of those mods, this mod is a good suspect to rule out.^[1]

Unverified The sources don't confirm which of those target mods are installed in this pack, or which of the optimizations are active here. Check the mod's config in your instance to see the real toggles.

Invasive Optimizations doesn't add machines, multiblocks or items of its own. It patches other mods to cut server-side tick lag, so the machines, pipes and pots you already use should behave the same way while costing the server less time.^[1]

The changes are called invasive because they reach into other mods' code. That makes them more likely to crash or break than a normal optimization mod. Each change can be toggled individually in the mod's config, which is the temporary fix while you wait for a bug fix.^[1]

What it optimizes

• Pipez: the biggest group of changes. They make connection and inventory fullness checks O(1), exit early from targeted functions, move work out of loops, cache tag filters, speed up NBT comparisons and cut Stream use in hot paths. The filter caching uses more memory and makes loading pipes marginally slower. The author also points to a separate Pipez Lag Fix mod for exponential backoff.^[1]
• SFM: caches item and fluid filters (regular, regex and tag filters for now). It uses more memory and makes first compiles take longer. It is an experimental change, so it is disabled by default.^[1]
• Botany Pots: hopper Botany Pots get exponential insertion backoff and emptiness tracking.^[1]
• Xycraft Machines: extractors check for redstone signals every tick rather than only when their neighbours update. Separately, extractors resort their recipes every so often, which is usually not necessary.^[1]
• Applied Energistics 2: caches AEItemKey::fuzzySearchMaxValue during init.^[1]
• Create: fails fast on clipboard migration in ItemStack.<init>, which reduces the cost of that very common operation.^[1]
• Placebo: passes a Supplier<String> in DynamicHolder#get so the string is only built on the cold path, and replaces CachedObject#hashComponents with code that doesn't use the Stream API.^[1]
• Accessories: avoids iterating a Map entrySet by accessing the underlying keySet directly.^[1]
• Pastel: removes Pastel's ItemPredicateMixin, which the author considers unnecessary and expensive.^[1]

Why each patch exists

The mod sorts every change into a category numbered 1 to 5. Category 1 is a patch that was sent upstream but hasn't been reviewed for a long time. Category 2 is a patch denied for reasons unrelated to quality, such as the mod no longer being maintained. Category 3 is a patch with no way to contribute, such as a closed-source mod. Category 4 is a patch already applied upstream but not yet in a released version. Category 5 is experimental or of dubious usefulness, and those changes are disabled by default.^[1]

Unverified Which toggles are on or off in this pack is set in the mod's config, and the sources here do not show it, since no config files for this mod were provided.

Invasive Optimizations has been in All the Mods 10 since 7.2, and the pack has updated it twice since then. Here is the version trail, release by release.^[3][4][5]

• All the Mods 10 7.2: Invasive Optimizations was added at version 1.0.19.^[3]
• All the Mods 10 7.3: updated from 1.0.19 to 1.0.22.^[4]
• All the Mods 10 8.0: updated from 1.0.22 to 1.0.23.^[5]

All the Mods 10 8.1 ships version 1.0.23 (invasiveopts-1.0.23.jar), the same version as 8.0, so this mod has no version change in 8.1.^[2][5]

Unverified The pack changelogs only record version numbers. The mod's own changelogs for these versions aren't available, so what changed in the mod between 1.0.19, 1.0.22 and 1.0.23 is unverified.
